I chose the TurboTax iOS app because it offered a $20 discount on the deluxe package. However, I was charged full price.

Turbo Tax Deluxe is currently discounted to $40. The regular price is $60.  Keep in mind the state is additional. If you have to file a state also, the price is currently $45, the regular price is $55. 

That is the issue.  I was charged $60 ($63 with tax).  I live in Texas, there is no state tax.  Any idea how I can be refunded the $20?
