I was wondering how you guys figure what your willing to pay for an item?

And then what? They arnt gonna offer you what the market value is. Do they use a formula or percentage? Read the question slowly .

In my experience wits been basically 70%/30% split. Pretty standard.

They only give u a percentage of what it's worth on ebay but I'm not sure what percentage it's lower then half tho I know that

I think they look on eBay and see how much you can buy an item for lol
