Chances are, you feel pretty strongly that you give enough of your hard-earned money to your state as it is, but if you're a resident of California, Connecticut, Missouri, Pennsylvania, Texas or Wisconsin who purchased a DTV converter box
from Best Buy, you may have donated a little extra. Reportedly, some Best Buy locations accidentally overcharged for sales tax when deducting the $40 government voucher
from the purchase price of DTV boxes, and now the retailer is looking to right the ship by doling out refunds. If you paid with a credit card, sit tight -- your check is in the mail; if you used greenbacks, don't even bother spending $5 per gallon to retrieve your $2.50.
