Your thoughts on selling

Hey, all.

I've got tons of vinyl that I never listen to.  I've sold in the past, but it was always a pain to grade as I never play-graded, but just visually graded prior to selling.  But...vinyl being vinyl, some records that looked pristine apparently was noisy once received and played by the buyer, which caused me to refund the buyer (both the cost of the record and shipping) putting me on the negative side of the dollar equation.  I also always told the buyer to keep the record.

So I'm considering doing this:  Sell the record but only ask for shipping cost and have the buyer decide what the value of the record is, with one caveat that shipping costs will not be refunded.  

Granted, some buyers will take advantage and say the Mo-Fi I shipped them was only worth 50 cents.  But I think for the most part folks will pay a realistic amount.

Am I being naive or could this actually work?  And by "work" I mean most folks paying a fair amount for said record?

Thanks,

Mamoru
