I have tried many different generic brands of diapers on my little ones over the years to try to find the best value. Kirkland diapers are some of the best that we have tried. Costco's Signature Premium Diapers are great for older babies. My son is two, and these did a great job at keeping all the yucky stuff in until we could change his diaper. There were no leaks, and he didn't develop any skin irritations from wearing them. I have been very pleased with Kirkland's diapers. As far as price goes, these are not the cheapest diapers you can possibly find. By catching deals on the internet or using coupons and sales in stores, you can get at least the same price (and sometimes an even lower price) for bigger name brands. However, that requires time and effort. If you're short on time, and/or just like to get all your shopping done at one place, Kirland's diapers will save you a little bit of money versus paying regular price for Huggies or Pampers. Since they work just as well, it's worth it to me to save both time and money on a generic but high quality brand.
