if your looking to buy in bulk theres a warehouse here on Rogers rd and Weston Rd that has a similar concept its great pricing and no membership need just letting you know its got great stuff in it not as great as costco but hey it works and has lots and lots of stuff
I'm a member... not at Costco but at Sam's, que no es lo mismo pero es igual. We go every week and buy numerous things (lately, mainly ice cream... ) We think it's worth it. But only because it's a la vuelta de la esquina from home. I wouldn't go far for Costco.
Another option is splitting the bulk of something with friends and family...
that's what we do. Well, my MIL has one, and we borrow it when we need it.

@ MJ - I think it's worth it, they got sooo much options & selection & great sizes. Just for an example my hair product (silk) is like 20-30 at trade secrets, salon, etc. for a tiny bottle at Costco is like 20 but I get the Huge bottle. Like this many other things will be good priced.
if you really need a massive tub of mayo that will sit in your fridge and rot 'cause its not humanly possible to use that much mayo before the bloody expiry date.. then yes... it would be worth it.
we usually buy stuff from there when we go camping or have parties, where we know we're going to be feeding a lot more than just the four of us... if u live closer to a Sam's Club go with them.. its the EXACT same thing as Costco and the membership is a little cheaper but everything else is basically the same.
