We combine the shipping.The cost for the shipping( 3.50$ for international) it's a flat rate ONLY!!!!.If you're want to secure the shipping and have trucking number it's going and cost you more ( 22 $ international). It's NO RETURN. For the customers who want to tell me what I don't know (I hope everyone understand what I mean by that).Please!!!! TAKE IT OR LEAVE IT!!! Don't waste my time!!!!! Let me know your decision about the shipping cost and I sent you final invoice.
