Just placed my order. This is how I did it if you are having problems.
1. Close the previous link you had and open it again.
2. Add a totally different lipstick in your cart. (For example: snob)
3. Go back and add the Riri lipsticks or lipstick that you want. (this bypasses the $1.00 shipping message that you get if you are only purchasing on riri lipstick)
4. check out and delete the lipstick you didn't want (in this case, Snob or what ever lipstick you threw in the cart)
5. Click check out and you should be able to place your Riri order.
HTH.
