Advice on grocery carts

I work at a pool construction company that has thrown out 2 old grocery carts used to haul parts around the warehouse. Both are fully made of metal. The yard I called said I could get around .08 cents a pound for them. I'm new to metal recycling and have been reading up on the best ways to disassemble and sell various items and metals for maximum profit; any advice for grocery carts?. All I am able to find online is information about carts being stolen for scrap. Thanks for reading.

Here's a link to the yard I called: http://www.americanrecyclinginc.com/pricing.htm

Also take any store labels off. My yard wont accept them if they have anything associated with a store still attached.
