Costco may not spring to mind as a go-to spot for beauty buys, but our research shows it's a great place for deals on many products you can stockpile, especially hair and skin care items. In store, Costco members can find good buys on drugstore staples and some salon-quality items in-store, but if you're in search of something special, don't forget to go online -- Costco's website has an impressive range of luxury beauty products for less.
Costco can be a great place to stock up on deodorant, especially if you're shelling out cash for individual sticks at the pharmacy or big box store every time you need more. One of the best in-store deals is a five-pack of 2.6-ounce Secret Outlast Invisible Solid Deodorant for $13.99, or $1.08 an ounce. Amazon, on the other hand, sells three of them for $11.91, or $1.53 an ounce.
If you're a Cetaphil devotee, Costco might be your skin care nirvana. In store, a 28.8-ounce tub of Cetaphil Moisturizing Cream is $15.99, or 55 cents an ounce; 44 ounces of Cetaphil Moisturizing Lotion are $18.99, or 43 cents an ounce; and 44 ounces of Cetaphil Skin Cleanser are $19.99, or 45 cents an ounce. Those are prices untouched by most other retailers. The best Amazon can do is $15.18 for 32 ounces of the cleanser, or 47.4 cents an ounce. Walmart offers 16 ounces of the cream for $10.93, or 68.3 cents an ounce.
STRIVECTIN ANTI-WRINKLE CREAM
Looking to turn back the clock a bit? StriVectin SD Advanced Intensive Concentrate for Wrinkles and Stretch Marks aims to diminish lines and wrinkles in just a couple of weeks, and many reviewers say it works well. Costco sells a 4-ounce tube in store for $99.99, or $25 an ounce. At Amazon and Walmart, just a 2-ounce tube will set you back $79, or $39.50 an ounce.
ROC RETINOL CORREXION DAILY MOISTURIZER
Costco also offers a less pricey wrinkle-control alternative, RoC Retinol Correxion Deep Wrinkle Daily Moisturizer and Night Cream, in packs of two 1.1-ounce tubes for $29.99, or $13.63 an ounce. Just one tube of either product is $16.98 at Walmart, or $15.43 an ounce.
EOS LIP BALM
If you've been shelling out more than $3 a pop for a tub of the popular Eos Lip Balm in the checkout line at Target or another big-box store, think again. Costco sells a six-pack of Eos for $13.99, or $2.33 each. The next-best deal is at Boxed.com, which has the same pack for $14.99, or $2.50 each.
OIL OF OLAY
Costco is a bonanza for any Oil of Olay lover, with several products available in store. Deals include $29.99 for 3.4 ounces of Olay Total Effects Anti-Aging Moisturizer, or $8.82 an ounce. At Amazon and Target, a 1.7-ounce bottle is $15.99, or $9.41 an ounce. An even better value is Olay Regenerist Cream Cleanser, which is $14.99 for a pack of three 5-ounce tubes at Costco; Amazon wants $20.88 for the same thing.
AMOPE PEDI PERFECT FOOT FILE
If your feet need a little extra TLC, check out Costco for an in-store deal on the Amope Pedi Perfect Wet and Dry Rechargeable Foot File. The file, charging station, five refills and a storage bag are bundled together for $59.99. You can find the file and charging station for $39.98 at Walmart, but buying four more refills would set you back almost $30 more.
KIRKLAND SIGNATURE SHAMPOO AND CONDITIONER
Though Costco sells familiar brand names including Pantene and Dove, the store's best hair care deal is usually its own Kirkland Signature shampoo and conditioner, which earn raves for being both better and cheaper than the name brands. A big 33.8-ounce bottle of shampoo is just $9.99 in store, or 30 cents an ounce. The conditioner is even cheaper at $7.49 for the same size, or 22 cents an ounce.
NEXXUS SHAMPOO AND CONDITIONER
If a salon-style brand is a must, Costco also has 44-ounce bottles of well-reviewed Nexxus Therappe Shampoo and Humectress Conditioner in store. Prices are $16.99 (39 cents an ounce) and $24.99 (57 cents an ounce) respectively. Amazon slightly undercuts Costco on the shampoo at $13.05 for a 33.8-ounce bottle (38.6 cents an ounce), but it's much pricier on the conditioner at $25.22 for 33.8 ounces (74.6 cents an ounce).
LIVING PROOF FULL SHAMPOO AND CONDITIONER
If your flat hair needs more volume, Living Proof Full Shampoo and Conditioner delivers, happy users say. A 24-ounce bottle of this luxury shampoo commands a premium $59 price at beauty product retailer Ulta, or $2.46 an ounce, and the conditioner retails for the same price. At Costco, members can snag a combo pack with an 8-ounce bottle of each online for $32.99, or $2.06 an ounce.
ORIBE SHAMPOO AND CONDITIONER
If you're a fan of Oribe luxury hair products, a Costco membership could be worth this single product alone. The warehouse club offers several varieties of Oribe shampoo and conditioner online for members only. One of the best deals is an 8.5-ounce bottle of Oribe Shampoo for Brilliance and Shine bundled with a 6.8-ounce tube of the matching conditioner, sold for $39.97. Jet.com has the same bundle for $56.94.
ACURE ULTRA-HYDRATING SHAMPOO AND CONDITIONER
Salon-priced products are still a pretty penny for most, but Costco can be a good bet here, too. It bundles 24-ounce bottles of Acure Ultra-Hydrating Shampoo and Conditioner together for $24.99 online. Over at Jet.com, the same bottles are bundled for more than $36.
NEUTROGENA RAIN BATH
Neutrogena's Rain Bath shower gel has some passionate users, many of whom roundly praise its fresh, clean scent. You can find a 40-ounce bottle in store at Costco for $16.99, or 43 cents an ounce. The next-best deal we saw was Walmart, which charges $15.68 for 32 ounces, or 49 cents an ounce.
One of Amazon's best-selling lotions, Aveeno Active Naturals Daily Moisturizing Lotion, is much cheaper at Costco. In store, you can nab 40 ounces for $14.99, or 38 cents an ounce. Compare that to $8.97 for 18 ounces at Amazon, or 50 cents an ounce. Costco also has 8 ounces of Aveeno Positively Radiant Daily Moisturizer for $19.99, or $2.49 an ounce. Amazon charges $12.29 for 4 ounces, or $3.07 an ounce.
The ubiquitous, well-loved cotton swabs have a zillion household uses, but they're a staple in any well-stocked beauty kit for quick touch-ups. You can get 1,875 of them at Costco for just $8.99, or .005 cents a Q-Tip. That's a slight bit better than the next-best deal, at Amazon. There, you can get 2,000 Q-Tips for $11.96, which works out to .006 cents a swab.
RAPIDLASH EYELASH SERUM
Looking for a way to fill out skimpy eyelashes or eyebrows? Costco sells two 1-ounce tubes of RapidLash Eyelash & Eyebrow Enhancing Serum for $49.99 online. At Amazon, you can get only one tube for just shy of $35, and other retailers charge $40 or more for one tube.
OLAPLEX NO. 3 HAIR PERFECTOR
Weak or damaged hair can benefit from a product like Olaplex, which reviewers says does a great job helping repair broken strands. At Costco, you can find two 3.3-ounce bottles for $32.99, or about $5 an ounce. At Walmart, however, you'd pay at least $19.47 for one bottle, or $5.90 an ounce.
MASON PEARSON POPULAR MIXTURE NYLON & BOAR BRISTLE BRUSH
Users of this luxury hair brush insist that it's worth the eye-popping price, leaving long, unruly hair ultra-soft, shiny and manageable. If you're up for a splurge, you can shell out $205 for it at either Amazon or Nordstrom, but don't forget Costco: Members can nab it online for just $149.
KIRKLAND SIGNATURE HAIR REGROWTH TREATMENT
Rogaine has long been the go-to treatment for men with thinning hair, but before you spend big, reviewers say Kirkland Signature Hair Regrowth Treatment is worth a shot. The Kirkland brand, which features the same active ingredient as Rogaine, is $16.99 for a six-pack of 2-ounce bottles, or $1.42 an ounce. At Target, a similar formula of Rogaine is $42.99 for three 2-ounce bottles, or $7.17 an ounce.
GILLETTE DISPOSABLE RAZORS
Disposable razors are never fun to spend big on, but Costco can make it a little less painful, offering several good deals on Gillette razors for men and women. For example, you can get the women's Venus Snap Embrace razor and 11 Embrace cartridges for $32.99 in store or online; compare that with Amazon, where the razor alone costs $7.65 and and just four cartridges cost $15.86. That means you'd be out nearly $40 if you bought eight cartridges and the razor.
