Two years ago, you would have to be up throughout the night if you wanted any hope of getting in on Amazon’s Black Friday device deals. Amazon has figured things out since then and it usually isn’t until the evening when devices start to sell out. Right now, the Amazon Echo at $139.99 and the Fire Kids Tablet at $74.99 are the first to show signs of selling out. Both devices are technically out of stock now, but Amazon is still taking backorders at the sale price with shipment dates pushed into December. Judging by what happened during Prime Day, if the backorders pile up enough, Amazon will no longer allow orders to be placed. So put your orders in soon if you haven’t done so yet.
