I pretty much only buy from a wholesaler, I do have material sheared from time to time, I have to buy the entire sheet or plate, but I get all of it, they don't stock drops. Another supplier in the area buys all sorts of odd lengths of BIG materials just in case someone needs 2' of 20" Solid Round, or 10' of 30" I Beam... Does a good business on Odd Lots, but has full size Sheet goods and plate, as well as some full length bar stock. I do some work for him from time to time and he reciprocates with minimal charges for some odd materials. or just trade. I have a few capabilities that his shop does not. We also have the high dollar shop that charges "By the Foot" Minimum 1'... They have a drop bin inside the place that you can dig through separated by Hot Roll, Bar, Plate, SS, Aluminum... They do a brisk business on Saturday mornings!
I think they charge $.95/# for steel Drops... SS is obviously more and aluminum in between.
