Just because an item is on sale doesn't mean you are getting the best deal.

We found these 4 times you should ignore a sale from Yahoo! Financially Fit.

1. Below-average deals. If that blouse you have your eye on is only discounted 15-percent, you may want to hold off since it's actually a below-average deal. Yes, waiting may mean missing out on your size and preferred color, but get this -- markdowns on clothing average 42-percent year-round.

2. October electronic sales. Discounts on items like cameras and laptops are only expected to get better the closer we get to the holidays. On Black Friday weekend, HDTV and laptop prices will fall 20-percent lower than the best prices they've seen offered before. And the best time to buy digital cameras is right after the holidays since the newest models hit store shelves in January and February.

3. Volume deals. For example, items offered "10 for 10-dollars" sound enticing but, unless you need all 10, it's probably best to just walk away. These deals are often just marketing tricks so retailers can clear their inventory quickly. Item limits can trick shoppers into spending more, as well. When a product on sale is advertised as "limit five per customer," it makes it sound scarce, encouraging us to stock up, even if we don't need all five items.

4. Flash sales. They're offered for a limited time, usually at online daily deal web sites - and entice shoppers to buy with the thrill of a bargain. The time restraint makes you feel like you've got to act fast, and many people end up ordering products and services they don't need or have time to use. In fact, 20 to 30-percent of vouchers purchased from daily deal websites like Groupon, are never used.
