Did they hear the package ticking or something? What’s funny is they banned your dap, but probably let other kinds of “shady” stuff in on a regular basis. Even amazon is getting weird about lithium ion batteries, you know they COULD explode, just like the Yellowstone caldera - cough, cough They should of packed your R3 with some weed or coke, that would have made it through no problem. Oh wait I’m thinking about my country! Ha ha.
