I made just one payment, $65.32 to Banggood by Paypal. This included the price of the item, shipping, and — what I didn't know or expected — customs clearance/forwarding with UShopVShip.
I never heard of UShopVShip before but from what I can put together, they're one of the companies contracted by Banggood to do customs clearance and final delivery within India. UShopVShip pasted the Shiprocket/DTDC label on top of the original shipping label from Banggood, which was shipped through Yanwen. The package was never opened by customs in India and it was declared as 'motherboard' even though it wasn't.
So the process appears to be that you pay a fixed and final amount on the Banggood app, and they forward from China to India with Yanwen and some company in India will collect it from customs and forward it within India on Banggood's behalf.
