Because a lot of us shop around, I figured it might be helpful to share experiences with different sites so we can see what to expect or avoid.

I'll start simple...

Bodybuilding.com

Great site with a large inventory, pretty good prices, will price match, and a 10% discount code is always available. Customer service is very quick to respond, and their policy states that they will grant store credit even for opened supplements. Definitely will be doing business again

Here's another:

FitRX.com

The thing I like about this site is that they are constantly stocking new products and send out a newsletter with coupon codes. Prices are hit or miss, but they have a lot of great deals. Shipping is extremely fast. Return policy seems lame, they do charge a restocking fee.

I only order from BB.com when buying online, i live in florida and with their florida warehouse i get things 2nd day at the latest. love the place!

Yeah, I used to go for BB.com all the time but I've found better deals elswhere, such as at

AllStarHealth.com

Surprisingly quick shipping, warehouses in California and North Carolina. Very good deals on a number of leading products, plus flat rate shipping. Return policy is solid, accepts opened supplements back and gives money back, not store credit, for total cost minus shipping.
