In other words, basically I wasted my money? I do also buy the fly more combos when I get a drone from DJI.I wouldn't use the accessory coupons as I normally get the Fly More combo's which have everything in them.
30 day refund is good, but I've never had to return any DJI product.
Discount on DJI Refresh only useful if you have purchased an expensive drone as it already cost's you 49 usd to get DJI select
e.g. DJI refresh for the MM is usd 39
