What buyers will ask (and what you answer)

Who pays for the Buyback?
You do. “Paid first by its own sale”; Onda sets aside only what's missing from your balance. Your buyer gets Onda credits, not cash.
What if the Prize comes out on the first opening?
The order is random. When the last Prize comes out, the price drops, but never below what covers your cost.
Does the buyer get a box with several things in it?
No. Every opening delivers one real piece from your inventory, and you ship it to them.
Do I have to be live?
No. Your box sells from your shop and by link; on your show it appears in the Show shop.
Does the AI make up pieces?
No. Design with AI only does the packaging; the pieces are yours, with your photos.
How much does Onda charge?
10% + MX$3 + VAT per opening sold. You see it in Review your box before you activate.

10% + MX$3 + VAT per opening sold
