Some of the prices seem a bit high:
Birth Certificate (change of sex), I feel this ought to be half the price of $9.99
40 & 75 Silver should not even be available, and silver prices could be lowered slightly:
150 Silver $3.99, 350 Silver $8.99, 1000 Silver $19.99, 5000 Silver $89.00
Still quite expensive, however if it was lowered too much the economy would crash, and Redcoat gear etc would be all over the show (instead of being sought after).
The slightly lowered prices would encourage players to spend that bit of real cash, which in turn would support the game. Also players who invest real cash are then more likely to hang around longer.
