Here are a couple of GREAT codes for Sally Beauty Supply online:
$5 off $5 order: 555655
Free Shipping for order over $1: 555202
Free Liquid and Powder Sampler kit: 444368
Plus Order thru Ebates for an extra 6% back!
I just did it and it worked great - just make sure your order is over $1 after the $5 off coupon. I bought 3 lip glosses, some lip balm, and some lotion for a grand total of $1.55. (Sabrina is going to gets lots of stocking stuffers!)
