I am not 100% positive on this, but when I asked the SA this same question, she said you have to exchange before the next billing period (so basically ~28 days or so from the day you bought it). After that, I am not sure if you can exchange and get the discount on the exchange. I would just call them to double check their policy.Hi
So if I have a jumbo and I want to exchange for a medium, I will still get to keep the 20% or 15% discount?
