Never try this, so,not sure
Yes.
Not if you bring the same debit card you used to purchase the items with..
On their website it says you will be returned your money in the same form you paid so they will just put money back on your debit.
I made a purchase with my debit card and got cash back for an item that I returned ($50 range). I didn't ask for cash it was just done that way.
Not sure but most likely.
