I've read about how poorly Penney's is doing, and I hope they can get it together because I like this place. I really like their exercise wear (I found these fantastic running bras for less than $20!!) and they seem to always have lots of stuff marked down.
They also have, at least in the women's section, quite a few dressing rooms, which I LOVE.
I discovered their ship-to-store option and am a fan. You find your items on the website (there are reviews for most things, also appreciated), order and pay for them, and have them sent to the Penney's of your choice. If you get more than $25 of merchandise they ship to the store for free. You waltz in to any register and give them your info (you need your phone number and the credit card you used, if I remember right), then they get on the walkie-talkie and have somebody bring your bag/box to the register. I recommend not going during a super-busy time if possible, but otherwise it didn't take long at all.
