Big news for local bargain-hunters: Macy’s Backstage is on the way to Westfield Montgomery mall. The existing Macy’s has completely changed its layout to make room for this new store-within-a-store, which will offer a mix of clothes, beauty products, housewares, toys and seasonal items at 20 to 80 percent off “regular” prices. Backstage is sort of a mashup of Nordstrom Rack, HomeGoods and T.J. Maxx, drawing products from Macy’s own clearance departments as well as overstocks and limited-quantity deals. With shoppers increasingly motivated by treasure hunts and markdowns, Macy’s is looking to open 45 Backstage locations by the end of this year. At Westfield Montgomery, you can start shopping there on May 1st.
