Anyone had troubles in the request of the free card reader?

[Funtsik]

Hello, I just register to have a square account and during the process of choosing the payment processor, I notice that there is a free card reader. This particular item could really help with the process of payment as my business is mobile and would be very accessible, but during the process of request it shows a $10 fee plus tax of course. Although I'm hesitant to purchase but do believe that square should not advertise something that may not be true or forget me if I may not be processing things right when requesting the reader. If someone can help, please do! All help is greatly appreciated
