You get a free case or a refund for your bumper. Not a free bumper. Although you could get your refund and just buy a bumper with it.
The question is, if I can order a bumper today, would I get a refund? Do I need to buy from apple store? EBAY? retailers? Do we need to keep our receipt?
I'd like to know that too, should I order now and get a refund later?
