Try the code THANKS. I used it for Edith and it worked. Not sure if it expired 3/31 or will go through April too.
Just know the bag is a return and could be a double or triple return. Both sites have a habit of continuing to resell used merchandise that looks used. So, if you can get free ship and no tax to try it out and it arrives in sad shape, you can always ship it back using their prepaid return label. Just make sure you let them know it is damaged merchandise (if it arrives that way - check it over for pen marks, peeling/scratched lock, loop and hardware, etc.) so they don't subtract the label cost from your credit.
What I love about shopping with them is that they always go out of their way to accommodate. Once I got a temporary credit applied to my account while the damaged bag (scratched up lock) was on the way back, so my credit card would not incur any interest waiting for the return to hit.
