Well I live in the UK and have bought up to 8 yards of fabric from sellers in the USA. They post in a flat rate envelope and I have never payed more $14.00 postage. I would check her feedback and see what sort of a score she has got for postage rates, if it is low then email her and ask her why her postage is so high. If you don't get any satisfaction from the seller then report it to eBay.
