I find it odd that the seller resorted to claiming shipping damage as if that somehow reduced his obligation. Unless the package is trashed, any damage to the contents should still be the responsibility of the seller as he/she was the one who packed it.

I have had a few people make this bogus claim of shipping damage for non-razors: a clock that was missing pieces (somehow they made it outside of the box), a trumpet mouthpiece that was bent (the seller admitted he knew about it but figured it wouldn't cost much to fix it), and a modem filled with shredded paper (though that's what he packed it in, he claimed that it was shaking during shipping that caused the bits of paper to get inside--it had nothing to do with the fact he didn't put it in a plastic bag before surrounding it with the paper bits). Unfortunately there are some unscrupulous sellers who resort to claims of shipping damage when they called out on their crap.

End of my rant. Lucky for you, your seller stepped up to the plate and is willing to make it right. That is a nice thing to find on ebay.
