I found this to be more true if you are buying well-known and better grades of just about anything, but some manufacturers don't feel that way about a low-end item. It shouldn't be that way, but rather than take a chance, we will continue to wipe whenever we can. We don't buy the cheapest stuff, but for most banners we can't compete using the high-end stuff, either. Once you get a few feet into a roll, you can get a feel for what's gonna be coming on the rest of it.
