And the funny thing is that there is already legislation in place to deal with this. If an online vendor has a corporate office, a warehouse or a brick and mortar retail store in State XX (that has a sales tax), AND if an online customer places an order to be shipped to an address in State XX,

Hi At least on the 53131, the first sign of wear out was an error message. I believe it was a self test message (checksum error). I could easily be wrong about that. We blew them out within 9 months of when they were first introduced. That was a long time ago. Bob On Apr 24, 2013, at 3:43
