It’s hard to beat a useful item for under $10. The Fridge Monkey is a rubber mat that has grooves designed to safely secure wine bottles in a refrigerator. The nice thing about the mat is its price and the fact that it can be removed when not needed. Refrigerator space is a premium so if you don’t need the extra storage, you can free up the space for something else. Also, many people convert old refrigerators into beverage refrigerators. The Fridge Monkey can be useful there for storing beer or wine bottles. Price: $6.75.
