Each bag comes in a paper wrapper with a sticker on it. The sticker has a bar code specificly for that rescue group. You fill the bag with returnable bottles and cans.
When it is full you peel and place the sticker onto the bag in the assigned spot.
Then simply take the bag and drop it off at your local Hannaford grocery store collection point. This happens to be pretty convienient since I shop there anyways. The collection point scans the barcode and the money collected from the returnables goes into their account. You have nothing to keep track of AND they provide the bags so you aren't out anything but your drop off time. It is a fabulous program and SO easy to participate in. Please consider helping out your local shelters or rescue group. Those nickels might not mean much to you but they can add up to a heck of a lot of much needed funds for the animals in need.
