I recently bought a Phantom 2 Vision during the free battery promotion, but since the retailer I bought from does not participate in that offer...I don't get the free battery. This promotion is advertised on the DJI website. When I contacted DJI, they said something about different levels of retailers. In the end, I don't get the free battery. This is kind of messed up. If I can prove to DJI my purchase date, shouldn't they provide the battery? After all, it's their promotion/offer. I love the Phantom and would have ordered it anyways, but kind of feel taken. It is a 160.00 battery.
