We had a Sam's membership and switched to Costco. One of the deciding factors for us was that we felt it offered a better selection, sent out the coupons, has the large online site and is just cleaner and nicer than the Sam's in the Milwaukee area. I live on the East Side (and used to live in Glendale) so my closest options are 27th and College or 76th and Good Hope, neither of which are particularly well-stocked, clean stores. It's as quick for us to hop on the freeway and head up to Grafton. They've also developed the area quite nicely in Grafton and there's a Target, Kohl's, Best Buy and Dick's there, as well as one of the large pet stores (don't remember which one.) Living on the East Side, we have to travel to run our errands no matter what, since there's nothing nearby. I appreciate all these things being in one place so I can run all the errands in one trip. Kirkland's brand has tested well against all kinds of brand name competitors, as mentioned above. Our main reason for going every two weeks is for dog food. I have two permanent dogs and am a foster home for a rescue, so often have more than just those two. We were feeding Iams, which is about $38 for 40 pounds, give or take and depending on where we purchased it. Kirkland's 40 pound bag matches comparatively (and sometimes better). It's well-received among breeders and rescues and it's about $26 for the bag. That right there paid for our membership. For the electronics geeks out there, my brother is one of those must-have top of the line, biggest and bestest kind of guys. He has a 70 some inch TV. He has surround. He has Blu Ray. He has it all and he's bought it all from Costco considerably cheaper than he found anywhere else. Most recently, they had a Garmin available in store and online for $100 cheaper than that model could be found anywhere else. I would think if you're contemplating any electronics purchases, this would also pay for itself. Plus, it's all available to look and compare online, which I'm a big fan of.
