I always approach a supplement store owner and tell him i want 10 tubs of protein (i know its a lot of cash all at once!) and they always throw things in for free or knock off 10-20%!!! I always end up saving 50-100 bucks this way!!!! Plus i'm lazy as hell and i like that i don't have to hit the supplement stores all the time!!!
I always go to GNC's brand of protein because it tates great and all GNC products are buy one get one half off, although I think they might be changing that. Plus if you shell out 5 bucks for a gold card, you can get an extra 20% off. All this can add up to some serious savings and good protein.
Anyone know a nice price place like proteinfactory in the EU? Shipping and custom fees are way to high if you order from the us, atleats the times I've ordered. Shipping about $25-30, custom fees about the same. That is a lot just to order 20lb of protein.
I used to get Protein Factory, but after reading on some botched orders (do a search), I switched to Prolab NLarge that you can buy at most health food stores.
Recently I tried ProteinCustomizer.com and the service was great. Cheapest I have found so far. You should try them. A new company and I highly recommened them.
