We Texans hate taxes. AND cheddar heads. eBay seller #2 is 40 cents more, but NO sales tax. WTF? How is one seller charging Sales Tax and another is not. Is the 1st one running a scam? Is the 2nd one going to prison? I've superficially read about people complaining about having to charge and pay sales tax for e-commerce, but didn't care enough to pay attention until now.
