As someone who tends to have something to renew on a monthly basis, the payment process is incredibly frustrating. I used to have a form prefiller configured for the payment page, but now that DH has switched processor (the integration could do with some serious style work) that no longer works.
It would be great if DH considered a modern payment processor that facilitated saved payment methods.
I've just encountered this. It is frustrating to say the least, as I too, make payments on a monthly basis.
This is the final nail in the coffin for me. I'm out.
Adios, DreamHost. It was fun while it lasted.
