I like the service (just used mailinator to test it) but in the end I'm left with the feeling there is some hidden cost to me. I'd like if it was clear that it was a free service for me.
I notice you are Australian? Or have you localised your site really well?
>You must not modify, adapt or hack the Service or modify another website so as to falsely imply that it is associated with the Service, ChargeBack.cc, or any other ChargeBack.cc service.
You must not do illegal stuff?
>ChargeBack.cc reserves the right to update and change the Terms of Service from time to time without notice
Please change your policy on this, tos-dr.info will likely rate that section badly.
Have yet to get a notice as a "merchant" but I love the experience as a consumer.
