You can get whatever you want. I believe everything comes in either 50lb or 55lb sacks depending on if its american, british, or european. Last time I bought maris otter it was about 70cents a pound and then generally its about 3 dollars shipping per sack. We use north country malt:

Their website has a full catalog.
I forget who got us the use of the loading dock/storage facility 2 group buys ago, but it was directly on Rte 17 in north jersey. Rommel, I remember you put it all together, do you remember who arranged that delivery point for us?
fineexampl, I think I remember golden promise being available, I think one of the companies that offers maris otter also offers the golden promise, check the catalog.
