Not sure; I always bought mine from wholesalers. You might try Ebay, or you might go to Ollie's & buy one of their blue tarps with grommets already in it; they're relatively cheap, and you should get a couple years out of it 'til UV or wind wrecks it.
I wonder if they make clear tarps? I was hoping to get something that let the light in and was see through, which is why I originally went with the plastic. But it's driving me crazy with its insistence on falling off the run at the slightest provocation, lol.
