I finally stepped foot in this Costco location for the first time today and what a treat! It was early afternoon and everything in the universe must have been in sync. I didn't have to park a mile away, there was no waiting at the membership service desk and they spat out a new card in no time. Shopping was quick and painless, with virtually no issues finding anything. There were lots of food samplers out to make the journey more enjoyable AND the time from entering the line to pay for the groceries to walking out the door with the cart was probably under 15 min., assisted by a high energy, friendly cashier no less.
I wouldn't be crazy enough to think that an evening or weekend could be as wonderful an experience, but workday hours rock.
