ames: In simple English… if you ever go shopping in NJ at the mall, or buy stuff from Overstock.com, etc. and save money compared to the NY sales tax… then make sure on April 15th you put all those out of state purchases on your NY tax return and pay the difference in sales tax (for the NJ stuff) and pay the full NY sales tax for the Overstock.com (and similar online tax-free retailers).
You will then have reached squeak’s madreiga!
PS to squeak: Do you have any good recipes for cholent?
