Target takes Manhattan, Chicago and Malvern, Penn.

Target is opening new stores this weekend and now's a great time to shop the chain, even if you don't have a shiny new big box opening nearby. The company will be rolling out new merchandise and expanding the selection of grocery items at existing stores.

Target will grand-open three new locations on Sun., July 25, but it's the Harlem location that really gets the star treatment. Celebrities like, er, the Seinfelds turned out for an event earlier in the week but it's the designers with whom Target has partnerships getting the most buzz.

In honor the first store in Manhattan, Target has released the Harlem Designer Collections including swimwear and towels by Isabel and Ruben Toledo; kitchen linens and tees from Chef Marcus Samuelsson; and urban apparel by Stephen Burrows. Prices range from $3.99-$19.99, and of each sale from the collection goes to a charity of the designer's choice.

But don't blink or it will be gone. Target is known for its "exclusive" designer partnerships but New York seems to have spurred Target to new levels of exclusivity. The Harlem Designer Collections are available only through Aug. 1, and only at the Harlem store, online and a smattering of additional "select" locations with a similar shopping demographic to the Harlem site.
