Wanted: Old VHS - blank or containing video

Hi, I'm working on an art project and would like video tape to use as material. Do you have any old tapes lying around and don't know what to do with them? (Cassette tape could also work?) Not looking for anything valuable, just unwanted tape. It could be blank/recordable tape or old movies. Doesn't really matter what's on it as long as it's video tape. I'm willing to pay a little for your trouble if you have a good quantity.
