I won two items from the same seller on Sunday

I asked prior to the auction if she'd combined postage and she said yes. I've not been able to get her to respond to my request for a new total. Now I'm getting worried, I've never left it this long before paying for my goods, is there anything else I should do? I don't really won't to pay double the postage and I'm at a loss as to what to do next, any bright ideas welcomed, thank you muchly in advance. 

Thank you **peaseblossom**, I just tried that but sadly it takes me to a link saying 'unable to access contact information', I suspect from the list of reasons it's because they only allow numbers to be given out in successfully closed transactions and this isn't as I haven't paid.
