The customer who comes in our store, will be coming back next week for a screenprotector
When he does, I'll ask the address where the ebay seller can sent the phones.
But yes, I need to know which airlines he would be flying, and I should give some commission to that person that will going to help me.

So the end price should be like "((total amount phones + commission to the guy) / total amount phones) + shipping costs = Phone price"
