Vision Insurance. Can WalMart charge extra $ 30 sale due on full retail as if you did not hold insurance?

I purchased my eye glasses at walmart with my Spectera insurance. I have to pay $ 15 co-pay for lenses and $15 for frames. So I owed $30 plus tax. BUT later WalMart charged me and extra $30 sales tax as if I be paying the whole $350 for the glasses. Is this court?
If you are accurate within what you are saying, of course it's permitted...They wouldn't be doing it if it were not legal...

Think around it, if it's illegal, a regular person approaching yourself can bust them...
Read your insurance policy. Wal-Mart is required by law to collect sale tax on items they sell. If the item is subject to sale tax in your state later they are required to collect the tax. Do not blame Wal-Mart...blame your government.


Answers:    Yes, because they are required to collect sales tax on the total amount. Just because the insurance company pays $200, does not exempt that $200 from sale tax!

But what a ripoff - most states don't charge sales excise on glasses.
