Carl's has raised the price on its food so that the $6 burger is now actually almost $6. The big marketing ploy here was that you could get a burger for just a few dollars that was the same quality as what other places charge $6 for. Not anymore.
Additionally, they have not resolved the issue of employees that speak so little English that they are unable to either take or execute your order correctly. We have emailed Carl's in the past regarding this issue and are just tired of having to bring it to their attention when they get the order wrong (which is most times now). 
We have now decided to just go across the street to the In N Out burger at Fiesta Mall for any future burger runs. You can get a burger for half the price and the employees speak English and can get your order right.
