Don't know where you live but in this money grubbing state of NJ you must collect sales tax on nearly everything! Just like admission to a movie theater or an amusement park...the state wants their cut! Charities may be exempt but I would call your local tax office to double check. I know many businesses that folded because they "didn't think" they had to pay until the state came calling a few years down the road & added on their fines & penalties, couldn't pay & had to close their doors. The tax man can close you down quicker than anything...double check BEFORE opening...avoid the aggg! Just my 2 cents!
