Insulin Pump Supplies- what do I do with all of them?

I use a Medtronic minimed insulin pump and have a TON of extra supplies. Anyone know of any places that do buy backs or where I could sell the sealed supplies? It would be a crime for all these extra supplies to expire or get thrown away when people out there could use them.

Thanks a good idea Liz. I said I was going to put my pump on eBay more for symbolic reasons as apposed of " profit" but I think I will use your idea  instead. Haven't had surgery yet so I'm hoping that after I do the pump comes off....well see.
