Sales Tax
Sales tax has not been 10% for a long time.
Shoppe Tax
Beware! Shops that do not pay taxes for more than two weeks may be subject to closure, repossession by the Governor, or even knocked down to make way for new buildings!
The "May" is very misleading -- there is no governor control.
Also, "repossession" is inaccurate -- it dusts, and must be rebuilt.
