How to save money at Costco

Costco shopping pros know this, but it can be a handy reminder. Click the "Warehouse Savings" tab on the top menu at Costco.com to find member-only savings. These specials vary by ZIP code, and delivery costs are extra, but the specials can be compelling.

Another savings tip that warehouse wonks use is to look for an asterisk in the corner of a Costco price tag. That means the item is being discontinued, and the savings might be better than average.
