I love American Eagle for graphic tees but I am all about Target for everyday clothes and Mervyns for jeans!
My bargain shopping tip is for formal dresses...
Start scoping out dresses around the time of high school homecomings and proms. Right afterwards, the prices drop down to an affordable fractions of the original price! I got my formal dress last year for about $50 at Hudsons and it was amazing! This summer I saw an incredible red dress marked down to $12 (

) and if it didn't have a visible and non-fixable snag, I would have grabbed it immediately!!!
