I’ve always just kept my old Apple Watch bands but after reading a few forums I thought I’d have a clear out. Little did I know but there is a collectors market when it comes to watch bands. This is because Apple discontinues certain colours for each season. I was very surprised when I sold my hyper grape Nike version on eBay for double the original retail price!
If you have bands lying around this might be a way to get rid of them for a good return.
