Thank you
CMIIAW, but you were asking how it works now (prior to April 20). If so, currently they give you back either the lowest price or the current price (I think it's the former), but since they never have sales, it is probably the same. They do not deduct 20% and the give you store credit. SO you can buy somethign for $100, use 20% off, then return it, get back $100 and you are up $20. That is exactly why they are changing the policy.
