Just a nitpick, while Texas' state wide sales tax is 6.25%, every local municipality is allowed to tax up to 2% for their own revenues. I have yet to make a purchase anywhere in the state in my entire life and not been charged the full 8.25%.
Texas also exempts grocery store food purchases from sales tax, barring a few specific luxury categories, so that's something to keep in mind as well if you have a large family. Saving 8% on food could be a decent chunk of change for a lot of families. Restaurant food is still taxed at the normal rate.
