We donated alot of VHS tapes to a local hospital earlier this year. Believe it or not, they still use VCRs in the patient rooms, at least on the children's floor. Each child has a VCR (rooms hold 2 children) They were happy to get them, they said they are hard for them to find now. (They had alot of tapes for young kids, like Barney, Pooh, etc. They liked that I had some tapes for older kids, not cartoons-- for the tweens and teens)
My daughter was a patient there a couple of times, so we knew they still used them. This was not at CHoP (they use DVDs) , but a smaller local hospital in NJ. Libraries also sell them at book sales. I am an active Ebay seller, but I saw no market for these, and the shipping charges are more than the tapes are worth. (IMHO)
Good luck!
