Around here (SF Bay Area, California) we pay the "deposit" but none of the stores (I'm aware of) actually buy cans and bottles back. I'm not sure how much the per can price is at the recycling places you have to take them to.
I was very surprised one time on vacation in Oregon when there was a can/bottle recycling machine right at the entrance of a grocery store. I walked back to it with an empty can from the car I had and fed the can into the machine. I was a little disappointed that all it gave me was a receipt to use toward my next purchase at that store. But if it was a store I went to regularly, it would totally make sense.
I live in Oregon and you can get cash from the store for that receipt. Some people (homeless, poor, frugal) collect bottles and cans from public trash bins for this exact purpose. Sometimes schools have fundraisers where you drop off bags of cans and then they take them in and get the cash value for them.
