A quarter sounds good, or at least is a good place to start
I have to admit I no longer return cans and bottles, despite that they’re more likely to get recycled when you return thenm. However I’ve been trying to cut back on things like soda anyway, and I’m not going out of my way for a dime to a quarter per week. They go in with the rest of the recycling. We did have a guy coming through collecting cans and bottles from recycling bins so I tried saving mine off to the side so he wouldn’t have to dig for them, but he hasn’t been around in a long time
