I've been trying to build an inventory of the most commonly needed materials, so that when I need a piece of this or that, I have it. Not long ago I bought some aluminum and black delrin rounds. Each was an assortment of sizes, cut in 12 in. pieces to fit a flat-rate box. Looking for some 1 in. dia. UHMW, I came across a deal, 1 in. dia. x 48 in. for $15 with free shipping. This was much cheaper than any other listing. Even weirder, it came from MSC. https://www.ebay.com/itm/28280256202

Yeah a great deal, ordered one when there were about 20 left.That's a great price with shipping, I think I'll get one of those. McMaster-Carr has it for $12.56, but that $25 shipping charge is a killer. I put two 2' pieces in my cart and shipping went down to about $10.
Looks like they sold out now.
