@Trust-Escrow did you use purse.io?
Purse.io anyways doesn't sell DJI products. They just sell gift cards to sites like Amazon, where you can buy the product. But I guess op was looking for a site to buy it directly from a site which accepted bitcoin.
Just chcked your tracking number, it seems to be pretty good that you were able to get the product in 5 days from Hongkong to Pakistan.
