Right now at The Body Shop you can get FREE shipping with no minimum when you use the code TBSFREESHIP at checkout. So take a look at their clearance and sale sections to see if there is anything you can use!
I tried the code at 7:15 a.m. EST on 10/9 and it works.
In the clearance section they have these Born Lippy Lip Balm Pot-Watermelon on sale for only $2! I was able to add 9 of them to my cart and get all the way through checkout so hopefully they have some decent stock! These would be an awesome addition to any small teacher gift!
