Just a couple of things about the nursing tanks and some good deals on nursing tanks right now:
babystyle.com has their Majamas nursing tanks and nightgowns on sale, plus an extra 20% off the sale price through this weekend with the code sale20. That makes for 20-something bucks apiece on some items that are usually $50-60.
babycenter.com has Glamourmom nursing tanks on sale for $35.10, plus there there are codes for an extra 10% off sale items OR free shipping on a $49 order (both codes pop up when you look at your shopping cart).
And in case you keep track of such things, babystyle.com is a member of the UPromise network, and babycenter.com is part of ebates.
Hope this helps someone out!
