Yeah, I'd say hyzerfarm is great. They're newer to the online sales arena, but are delivering a high quality disc purchasing experience and with great prices. Unlimited discs ship for only $5
They already have over 4,600 listings, nice photos of their dyed discs, pick your weight and color for non dyed discs, and discs for sale from 9 manufacturers.
It takes little to no effort to at least click on the link and check out this new online place to buy discs.
Oh and did I say yet that unlimited discs ship for only $5??
