Hey gang, I've done business with
Baytec Containers before and they seem to be reputable with decent prices. My last purchase was for used, food-grade 55-gallon and 15-gallon blue plastic barrels. They run specials on shipping and other sales pretty routinely, so it pays to check their site from time to time. When I bought my barrels, I was looking for used barrels on sale with free shipping. Eventually, that combination/offer came around.
They also stock new 5-gallon pails and a variety of gamma lids. I'm thinking of purchasing my buckets from them for grains and other things I want to keep from the elements. Their 5-gallon buckets are currently on sale for $4.29 each (they get cheaper if you buy in quantity), and gamma seal lids on sale for $5.95 each (again, cheaper in quantity).
Not sure what kind of prices other folks are getting for these types of things, but Baytec seems very reasonable to me.
EDIT: They also have mylar food bags and oxygen absorbers.
