hi Sara,
Thanks for your comment. Even before we started this site, we were already taking photos of stuff at Costco so that we'll have the info when we get home...sometimes to compare prices, sometimes just to research a product more before we buy. We thought that maybe other people may want the same info as well. So we're happy to hear that you find the site useful!
Costco is definitely one of our favorite stores and it's helped us to save time and money shopping there, even for our small household of 2 (sometimes 3 or 4 when we have guests) :)
Regards,
Olli
