Alternative Premeir Payment methods?

For reasons I need to keep private my wife has limited my internet access. I had to allow this to keep peace in the house. Anyway, for these reasons if she were to see an internet based charge on our bank card that she didn't make I would be in a lot of trouble so I need to find alternative ways to pay for things I need/want online. I am asking if there is an address or way I can send payment for Premier Library and have my log in info e-mailed me after payment is recieved. Thanks.
