As I wrote on the previous page - look to Paraguay for contraband heaven.
I spent a bit of time in Ciudad del Este. There’s a bridge there over the border with Brasil called the Puente de Amistad. There is a steady stream of ‘smugglers’ literally marching across from P to B carrying all kinds of electronics etc. Trucks too. The customs agents don’t stop them for anything but bribes. Those agents have historically gone ‘on strike’ for raises and benefits — by actually doing their job and thereby completely gumming up a significant sector of the Paraguayan economy. When they get their raise they go back to taking bribes instead. This relationship to regional trade goes back to the 19th century there.
