Smarter Ebay sellers..... nope DUMB Ebay buyers

At first read, I was in agreement with the OP. Does sound like it should be simple and cheep...right? But plastic prices have gone up a lot, and if you don't have a template...
He is using 6MIL, which sounds about right. $25 for a 10x25... Shop 10-ft x 25-ft x 6-mil Clear Plastic Sheeting at Lowes.com I figure I could get a few sets out of that. I was lucky to get my plastic for free from the warehouse I worked at at the time. My old ones were in little bits, so no template to cut from. So, I taped it up to the door and pretty much hacked mine out of the sheet. Didn't look fancy, but functional. For the time I spent screwing around with it, I would have gladly paid someone 20 bucks to cut them out for me. LOL.
If I actually wanted them neat, the ebay auction starts looking like a pretty good deal.
