If I remember correctly, shipping was free and there wasn’t tax for the state I live in at least. Not sure if that’s across the board.
I sold mine on eBay. Took a bit of a loss but netted around $350 for my 512. If I got $100 less or so, I might not have sold it.
I hear you. I don’t want to go too wild. Figured getting the oled was a good time to find out about new things and see if they are worth messing with.
