If you are talking about retail in stores... August... right now is great. 2013 stock is coming in for 2013 and Augustn 2012 is the kill season. They need to get rid of their 2012 stock to fill in their 2013. As the weeks go by, you will see more desperate sales... until Christmas. This is the rock bottom of their last years stock.
It's timed perfectly for Christmas. What is left over is on sale not for you as a buyer, but, to draw you in for Christmas shopping. All the rock bottom pricing is junk they need to get rid of... and, even better, items they have brought in at fantastic prices so you can comb around and buy higher priced items for Christmas out there for you to grab. These items... which are good deals are there for one perfect reason. For you to keep looking for other items. If you see a sale...BUY IT!
