$4.95 sounds a lot more reasonable, so all's well that ends well.
Though I'm not really an ebay buyer (or seller, for that matter) I do know what it's like to have a seller demand unreasonable shipping fees. Sometimes it's unavoidable if you really want your product, and they know that. One time I bought a nice razor from the SRP classifieds, and the seller demanded $20 for shipping after I paypal'd the full asking price. I agreed, thinking it was going to be priority and insured up the wazoo. More than 2 weeks later, my razor arrived in an ordinary cheap tiny bubble envelope, not tracked or insured. Not sure what my $20 paid for, but it wasn't for postage, that's for sure.
