That is a smart question, and it really does come down to a few factors. First, consider the transparency, and if you can, then do so. Always check out the reputation of the place you are buying the bodybuilding gear from. It depends a lot on the brand. Some companies offer better deals and more personalized support if you visit site directly, whilst others don’t have much of a difference to retailers. Also see what discount options you have, and whether you could save more buying in bulk.
