I've had a Kirkland/Costo 22" bag for about 6 years, and it had gotten to the point where it needed to be replaced. It was still functional, but the wheels needed some serious TLC, and there was quite a bit of wear in other places. I'm a pilot, so its seen alot more miles than most, and I was very pleased at how well it held up for the price.

As some of you know, Costco has a life time money back guarantee, and I decided to take it back, even though I didn't have a receipt, and there has never been a membership in my name (I purchased the bag using an employers membership). I walked out less than 5 minutes later with $70 in my hand! I wanted to just exchange it, but he said they no longer carried that model. Because of that, I purchased yet another Kirkland bag off their website, using my g/f's Costco membership. I figure that I'll just bring it back in another ~6 years and get my money back again!
