I love home shopping, but I always check the reviews before buying stuff. Just like any other things i buy, I find I save a lot of trouble from other people's experience with these things.
But they do sell some really good things - Candle Impressions flameless candles are one of my faves, and Tempt-tations bake ware is really good, and a good price.
A lot of stuf is hard to resist so I try to only watch when there's a reason to shop. The rest of the time there is usually some crab show or ghost hunters to take my mind off it.
