Other shopping tips for Costco

Did you know Costco price codes have a secret meaning? Manager special prices end in .97, closeout inventory deals end in .88 or .00, and discontinued items will have an asterisk.

You may get away with shopping at Costco with no membership by using a Costco Cashcard. Only members can purchase and reload these, but anyone can use them.

Also, Costco offers a price protection guarantee on any item for 30 days so if the price on your purchase is knocked down within that time period, bring it back with you receipt to get reimbursed for the price difference. Everyone already knows but we'll say it anyways, if you're eating on a budget, Costco's food court is where it's at. You can't beat the $1.50 hot dog and 20-oz soda!
