Double cashback? Why stop there...

I decided to transfer my credit card balance over to a new card to save me throwing money away on interesting, so after a quick check with the money saving expert I decided to go for a Texaco card. During the sign up, I chose to give up any cash back rewards in favour of a better interest rate - but the next page still proudly boasts:

Cashback Rewards: 0.00% You can DOUBLE this rate for purchases made at Texaco sites.

Seems like a fairly basic UI blooper there, not that it breaks anything of course - just makes them look a bit poor. Although it was slightly amusing, so it's not all bad :)
