There is an mx anywhere 3 for sale in the market for 4k, when i know it was available for sale at 3k at that time. Here's my proof. I bought it the next day. The seller has probably masked the price in anticipation of this. Is it considered gentlemanly (not legal, which is a much lower standard) to buy things on sale and then mark it up and sell? Essentially this is what retailers do, so i don't think this is wrong. But I've seen plenty of people do this, and plenty get frowned upon
