Perhaps you could make the Wood boxes an add-on for additional cost, so those who are trying to save some money and dont need the box, may be able to save a little.
Perhaps you could make the physical coin an add-on for additional cost, for people who just want the bitcoins and are trying to save some money.

video review of that coin.
Anyway, current bid is 2.8 BTC.
