For US folks, best way to describe this place is a cross between Walmart SuperCentre and Costco/Sam's Club. Prices are way cheaper than regular supermarkets, but you are mostly also buying in bulk. It's divided into three zones - 1st zone is a bit like Office Depot/ Toys R Us (and also has a couple of clothing racks) then the middle bit has lots of kitchenware/ household goods, etc and then the last section is all frozen food and produce.
Membership is free and you get two cards plus a token to get the cart. I have been here twice and purchased food in bulk for parties. I reckon the other best value purchases are also for paper goods- dairies, calendars, pens, etc. read more
