I always save pop cans and bottles, and plastic water bottles for the deposit. It is always amazing to me that people are too lazy to recycle them, let alone return them to the store to get the deposit back. I have to remind my kids not to rip the paper labels off water bottles, since the barcode on the label is what is needed for the refund.
It is also rather ridiculous that the aluminum can deposit/refund rules haven't been updated to reflect the increasing numbers of non-carbonated drinks in cans now. Only carbonated drink cans have deposits/refunds on them, per the original wording of the law.
Many groups use the can/bottle refunds as a fundraiser - they put out bins to collect them in, or have a mass drop-off day, or have an agreement with the "nickel-back" places (rather than return your bottles/cans for cash, you can tell them to credit it to your church or the boy scouts, etc.).
