The Clearance sale at Toys'R'Us that I mentioned a while back will be ending on the 2nd of August. "Brown" tagged items are currently at 70% off so you can snag some serious deals before this goes away.
Target is currently running its Summer Clearance sale. You can find items at 30% off and 50% off. If you want them, buy them, because they will not be there later. I know this because I made that mistake. Considering a lot of stores started with items at 50% off it may not last long.
Kmart is also running a sale of 75% off Clearance items. I do not know how long it will last.
