I heard about supplementsatcost.com from a friend, they have a $20/month membership but if you place 1-2 orders a month you still save money vs. most other stores (unless somewhere is having a fire sale) The membership is part of their affiliate program where you can have friends sign up and type in your member id# and you'll get $10/month/referred friend. I signed up 3 people in the 1st few days and my membership is free plus I get $10/month into my paypal account.... they sent me a free shirt with my 1st order, pretty cool stuff!
