Peter Thomas Roth has this "Travel Bundle" free with any purchase, as well as free shipping for the weekend.
If you grab one of the $3 travel items (lotion, conditioner, etc) it counts as a purchase.
Travel Bundle Product Page: Ignore "Out of stock message"
NOTE ABOUT "OUT OF STOCK":
The Travel bundle page says the item is out of stock, but when you put any item in your cart and hit "checkout" the travel bundle AND free shipping are added automatically to your order.
Use coupon code: 15OFFPTR
you get 15% off the $3 and it comes out to $2.55. (also, some $back sites have PTR for an additional few pennies off if you want to extra slickdeal this.)
This might be a site error and your order might be cancelled, so YMMV. Figured for $2.55 it was worth a shot for a cancel.
1. Add $3 travel item to cart.
2. Click checkout from cart, (you have to sign in to get to checkout).
3. Use coupon code 15OFFPTR
for 15% off.
Hope this is an ok SD, I don't find many deals to post that aren't already posted, so I hope I did it right.
