Discounted items are definitely a steal, especially if you've been craving for them since day one. I once went to Mango and saw this beautiful LBD that i simply just had to have! Of course, the price tag made me want to bawl like a baby, so I made a promise to hold off until the sale season comes along.
Finally, the LBD was on sale. I bought it - together with a handful of other items. Guess what, I ended up spending more than I would have if I just bought the dress before the sale! 
Although everything was a "steal", perhaps shopping during the sale season empties my pockets more than during regular days. How about you, have you noticed the same thing happening when you go shopping for sale items?
