Taxes stress me out. If the government could easily send me a bill of my sales taxes at the end of the year I might prefer that but given the system we have I rather pay at time of purchase over manual and more error prone tracking over a year.

Regardless, and maybe it's not a great distinction, I find a difference in a company not charging sales tax vs a company sending an excited e-mail about how they've found a loophole to avoid sales tax. Maybe that's just me.
