This is the closest Costco in the vicinity and I've been using them since I moved to this neighborhood, i.e. for 7 years now. Sadly, it's getting worse every year. Don't even think about coming here on a weekend unless you decided to skip your leg/cardio day. The parking is completely packed. You end up waiting for half an hour for a spot or alternatively park at any of the adjacent plazas (PetSmart/Staples, Home Depot). It's not too bad inside (you still have to wait for 5-10 mins in the cashier's line), but be prepared to wait for 20-35 minutes if you want to use their pharmacy. And you can't pay for your medications in the main line, so you have to use 2 lines. But no worries, they are building many new homes around here, so it's gonna get worse!
