It's hard to start walking around a Costco store without noticing something you never thought you would see there. It could be a $1,300 casket or the $3,000 four-person outdoor steam sauna, or something completely different.

Diamond rings at Costco start at $380 and go up to almost $20,000. To give an example of how a warehouse store engagement ring compares, consider a diamond platinum ring for $2,000 at Costco. It outdazzles a similar ring from jewelry specialist Zales that would set the proposer back $2,249.

At Walgreens, the package costs $90, but that's the way the diet cookie crumbles.
