Stawks, if the vouchers are valid, then yes, eBay will be footing the bill. They're not expecting you to do the discount out of your pocket. (I wouldn't imagine).
In answer to your $2 purchase question, you would find that the maximimum discount would be $2. eBay wouldn't let everyone buy something for $2 nd then give them $8 cash iykwim.
As it appears that the things aren't real, I guess you can say they have been foistered on you, as it you that has to deal with customers saying "my code won't work, now I don't want the item"
In theory, eBay are giving away what appears to the buyer to be $10, but it doesn't really cost them that much. It's sort of like when you get a meal comped at a restaurant. To you the meal may be worth $100, but to the restaurantaur, it's only about $33 cost price.
I'm figuring for eBay each voucher would cost them about $8 - so not sure why it's a good thing for them to do.
anyway, that's my take on it - I'm more than likely wrong though.
Some people can go their whole lives and never really live for a single minute.
