The metro area's retail economy is nothing short of unstoppable.


  Figures released today by the State Comptroller's office shows sales tax receipts,             which is the best measure of sales of taxable items, up an amazing 11.24% in September when compared to September of 2012.


  If the rest of Bexar County is excluded, the City of San Antonio's tax receipts are even stronger, up more than 13% from the previous year.


 By comparison, statewide sales tax receipts for September were up about 5.2% over September of last year.


  Just up the road in Travis County, which includes Austin, sales tax receipts increased 4.49%, less than half of the Bexar County increase.


  Admittedly, some of the increased sales tax collections comes from the fact that the tax itself went up by one eighth cent in April due to last fall's approval of the Pre-K for SA program.  But that small increase is not nearly enough to account for the huge jump in sales tax receipts.


  This continues a string of strong months for local retailers, and indicates a solid Christmas season ahead for the region.


  It will be interesting to see what kinds of sales tax numbers are put up for October, to see whether the furloughs of government employees due to the shutdown will show up in lower sales tax receipts.


  Strong sales tax collections are good news for local governments, especially the county and city governments.
