Feel free to ask any questions before purchasing.

I’m happy to offer combined shipping. If it doesn’t work for you for any reason, please feel free to contact me.

If you add multiple items to your cart and try to request combined shipping but it doesn’t work, the first thing to try is logging in to .com and making the purchase from there, then requesting combined shipping from that site.

Regardless of this, if it still doesn’t work, I will always partially refund the shipping cost, and I’ll be happy to combine the shipping for you.

Due to the currently ongoing U.S. customs restrictions, unfortunately I have to ship to the United States at a higher cost. Thank you for your understand!
