Many times it was because it was such a great sale we couldn't pass up a terrific buy. In the end, that turned out to be a money WASTER!
If you find shortly after the purchase you really don't LOVE it, take it back. But be careful...may stores have a no return policy on sale merchandise. It is best not to buy it in the first place, so remember that in the future. Have some sitting in your closet now? Time to donate those! Maybe there is someone out there that would truly LOVE it! And--shop smarter in the future.
