so last week me and my brother bought a roku streaming stick+ it was on sale so it was only 39.99 so we backordered it (they were out of stock) we didn't know what backorder ment at the time so we got a email saying that we had backorderd it and we would get one when they were back in stock. We did not charge for it yet so I was thinking will we be charge the discount price when we ordery it or will we be charged the standard price
