What is the difference between bottle drop and bottle drop plus? It says i can get 20% more from bottle drop plus? How does this work? Thanks to whoever can answer my questions!

You can redeem your refund at a kiosk at certain grocery stores for an additional 20% in the form of in store credit.

Rather than getting cash for your redemption, your redemption value is placed on a card (barcoded for identification). You can then use the card at various participating stores to buy things. When you do this they add 20% to your redemption. So if you plan on using redemption money to buy more groceries at Fred Meyer, an extra 20% is a good deal.

Its do it yourself machine take most bottles and cans 0.10 per bottles
