Come to NJ, some of the most confusing tax laws in the land.
Candy - taxed
Twix - not taxed (it's not candy, its a cookie bar)
Soda - Taxed
Hawaiian punch or iced tea - not taxed (soda has carbonation)
Bleach - Taxed
Laundry Detergent - not taxed (detergents is a cleanser, bleach is not a cleanser)
Oh, and in the County I live in, we have some of the last Sunday Blue Laws in the Country. You can buy food, but not clothes. You can buy liquor but not glassware to serve it in. You can buy nails and screws, but not the lumber to use them with. Bookstores are open for the selling of books, newspapers, and magazines - but they can't sell electronics such as an eBook reader.
As far as coins are concerned, It doesn't bother me. You shouldn't have more than 4 in your pocket at any one time anyway.
