I Think I'm Getting Hosed On Ebay!

I won this Saturday. The seller emailed Monday with the shipping charges, said 'it seemed a little high, and that she wouldn't blame me if I reconsidered."

I immediately emailed back asking if there was maybe a cheaper way to mail it, because I did indeed want the bowl. I sent another email yesterday because I didn't hear back from her.

Now it's Thursday, and she's still not responding!
Did I broach Ebay etiquette? Did I piss her off?

What if I pay the ridiculous shipping fee and she doesn't send me the damn bowl?

Aarrrrrgh!
