Just wanted to let you know about a costco experiment I tried. I was on the fence about buying a $55 membership, but heard great things about costco. I decided to try it out for a year and see if it's worth it and it is!! I used to shop at sobey's. I still do sometimes to get their sushi and other things costco doesn't carry. I actually kept track of the difference in prices/sizes of products and after one month I already made my $55 back in savings. I am also going out less to buy things since many products come in large sizes which helps free up some time. What do all you think of costco?
