Haha. I live in MA and there used to be a 5% sales tax. I worked at mcdonalds and people would always come in high and get 4 things off the dollar menu, amounting to 4.20.. They would always think it was the most amazing thing ever.."whoaaa 420 heeheeheehee *om nom nom*"
Damn I wish my state had 5% sales tax instead of 6. Not because it would be cheaper, but just for 4.20 to come up more often. You pretty much have to try to do it with 6% tax
