I'm using amazon lately for my supplements because i've found the cheapest prices there. Also amazon commits to be a very good service retailer. I have ordered my last five supplements in Amazon and I'm very pleased with service and prices. Try Amazon. Is good.
I've bought my last two supplements from them. prices were <50% retail. Only bad thing is that there are different "stores" within amazon, so quality of service and ship time varies.
I think Amazon is one of the best places to shop for supplements. I received my SizeOn about 12 days after ordering it. Not great, but I do live in Canada. It was 20 dollars cheaper then if I were to buy it from any store here. Will shop again!
Surprisingly, they have quite a large selection of products. Sometimes they ship from different places so shipping can be whack, but you can find some pretty good deals here.
