So there's these Amazon return stores everywhere that look like permanent flea markets. Walking around I saw this little guy for 5$, an external Bluray writer. Not bad, not bad. The QR code just links to a short manual. edit: it's a Matshita BD-MLT UJ-260 according to device manager.
They seem to be popping up everywhere. It's chaos, and you need to go often to find interesting items. Don't get swept up by FOMO, there's always more crap in an endless avalanche of trinkets in torn boxes. Also, the prices change day by day, when the crap is fresh it's like 20$ a table and towards the end of the week it's 5$ until the trucks come to replenish the piles.
