To Save Money
A fridge without a freezer can be cheaper than a regular refrigerator/freezer combination. For example, a Whirlpool fridge/freezer with icemaker is priced from around $899 to $1299, depending on bells and whistles. But a basic Whirlpool freezerless fridge starts at $617. Get a compact refrigerator and this price disparity grows even more. Compact fridges start around $100, according to an online search at Best Buy.
Another specific way you might use a freezerless refrigerator to save money is to use it as an ersatz wine fridge. If you're a real oenophile, you know a wine refrigerator can be quite expensive -- a full-sized wine fridge can run up to $1,000. However, if you just want to store your wine at a constant temp and aren't all that concerned about the utmost perfect temperature, a cheap freezerless fridge can be an inexpensive alternative.
