Costco is worth it if you want to buy in bulk. Not massive bulk, but bigger than you would buy in the supermarket. They do offers throughout the year. I find their meat and fish is good.
I don't know if they will let you in to have a look around before joining???
hi, the only way to do that is to go in with. Someone who is already a member, if you do happen to join, you make your Money back eventually when they do special offers.
