Important Q&A for U.S. Buyers

Pricing clarity

Q: Why do other stores sell the same product with shipping at a much lower total price? Why are your items more expensive?

A: For U.S. buyers, we use DDP (Delivered Duty Paid) shipping, which is safe, reliable, and recommended by eBay. Your total checkout price already includes item price, international shipping, import duties, taxes, and handling fees, so there are no additional charges upon delivery.

Some stores that appear cheaper may not include import duties and related fees. You might need to pay these separately, delaying delivery. Other sellers might falsely declare items as "gifts" or use untracked shipping, which is not legally permitted.
