Don't know about the AT250 price (as we have the DVR Advantage), but as for the sales tax, we live in Martin and according to our March bill, we have $0.42 for STATE/LOCAL TAX (SALES/GROSS RECEIPTS). This is not the 6% of the total bill, so I am not sure what the tax is on.
Yes, that is the new price. There have been numerous conversations since late December about this price increase that was effective with the February billing cycle.
