You can go to just about all the hydro supply spots on the internet and they'll have a number to contact them or email them. Tell them what your looking for, your price range, then go to the next guy and price compare. Got a brother-in law that does this to just about every thing he buys and I cant be-leave the prices he gets most of his shit for. I myself went and sent a bunch of emails out asking for nute samples, got a few free and got some for just shipping cost. Deals are out there and a lot of places willing to cut some prices just to make a sale. Give it a try, you never know.
