Air Conditioning Units

Summer is gone for good, and stores want to clear the space. “These units take up a lot of potential holiday shopping real estate, so stores will want to clear them out,” says Pavini. P.C.

Denim

Retailers began discounting last season’s denim in September — but for the old styles that still remain on shelves and racks, the price cuts are even steeper this month. For example, find tons of designer denim currently on sale at Nordstrom and Bloomingdale’s. Of course, you could wait until Black Friday for more serious steals, but if you want to get a head start on fall fashion, this is a great month to strike. “Some jean specialists, like 7 for All Mankind and Levi, offered their best coupons of the year” in October 2010, points out Lindsay Sakraida, features director at Dealnews.com.
