Normally a special deal is precisely that, a special *deal* - i.e. you get for free, or at a reduced cost, something you would normally have to pay full price for. If you miss a deal, you may kick yourself for missing an opportunity for saving money, but you can then purchase whatever was on the special deal at the normal full price.
The OP's original question, is therefore, is very logical - having missed the chance to get Jazz Drums for free, the natural next thought is - "ok, how much do they cost normally".
