The rising cost of food has prompted many people to buy freezer-only units, according to The Houston Chronicle. The idea behind this kind of purchase is that you can buy food in bulk at cheaper prices, freeze it and eat it over time at a great savings.

But Clark is not so sure about this idea. For one thing, not all food tastes good after being frozen for months. He also doesn't like salespeople pushing a freezer full of food on you. It's all smoke and mirrors because the samples you see in their freezers won't necessarily be what you get in yours.

Instead, Clark wants you to be a more careful shopper. Using a site like CouponMom.com can yield more savings in the long run than the freezer investment.
