...you should know about!
Erica told me about this great website, www.retailmenot.com. It has coupon codes for just about every online store you can think of. I've used it quite a bit to save money on things like free shipping and discounts. Definitely a favorite site, check there before you check-out when doing online shopping!
Two more deals that apply to teachers you might want to know about. I blogged about this before, but you can get 15% at J.Crew if you mention that you are a teacher. And I just learned that Ann Taylor Loft does likewise. Also, J.Crew offers a 10% student discount.
