problem with registering daemon tools

[estimablesir]

So, i finally decided to register daemon tools, but to my dismay i saw this message

Note: Important product-specific information such as the invoice or license key will be sent to you by e-mail. Free e-mail addresses are not accepted for online orders paid by credit or debit card. Click here for more information on how to order using a free e-mail account.

I'm not comfortable with the bank transfer or cash/check options. I have a gmail account, is there no chance that I could register with that email address?
