If you bought or are buying the Spark at B.B. they are now offering a $50 gift card in addition to the sale price of $599 (fly more).
If you already bought one from there, call and they will give you the gift card.

Hi, guys. I would recommend users buy our products from our website or local retail stores. Thanks for supporting.

Best Buy is a local retail store but thanks for the advice.

When I try to buy Spark Fly More Combo directly from DJI it says:

699 euros is about 830 US$ by today's exchange ratio.
Local retailer has even higher price.
And in BB it's effectively 550US$ after 50US$ gift card.
No matter how much I like DJI products it's really hard to justify the price difference of 280$ which is 50% more expensive. Especially since all the products are basically made for US market only (i.e. for spark it's 30fps vs non-existing 25fps, or 500m vs 2km range etc...)
