Source of grains

Does anyone have a good source of bulk grains at good prices with reasonable shipping cost?  I live on the coast of SC and the only beer supplies are in Columbia and they do not sell 50 lb bags.  My friends are visiting too much and the beer consumption is great.

North country malt has a great selection and good prices too.  If you order enough they will ship it freight instead of fedex and the shipping price per bag will drop significantly.  

northcountrymalt.com

alternativebeverage.com in Charlotte has good prices on sacks of grain, but shipping could offset the savings.

morebeer.com is in California and has higher prices, but ships free UPS ground if you're over $49.
