Might also be an idea if it's a new member to see who's behind the account, I mean most members are in reach of each other.
I for one would be happy to check out a new member here in the Netherlands selling a high value item, we know most of the Amiga users here.
But that goes for all countries, I can imagine large countries like the US are a bit thin because of the distance their, but hey, if you are in the neighborhood, why not ?
For me, high value items have always been sent maximum insured and maximum protected.
For instance I use the Post NL boxes to comply with their sizes and then I pack the item in an Ikea Salma box, the item ofcourse in an ESD bag!
The whole box is taped shut even on the inside and paper towels inside to deal with moisture and temperature.
With a high value item I usually didn't charge for postage, unless it was ridiculously high.
On selling within the Netherlands I even went to deliver it personally.
I have also learned my lesson with Paypal and Ebay, both accounts were closed 2 months ago after years of inactivity anyway, but it was with none computer products and low value back in the days.
I for one have had it with scammers and also on the Dutch version marktplaats.nl which was bought by Ebay a few years ago.
So if a new member sells a high value item in the Netherlands or even Belgium for that matter or near the border on Germany I'm willing to check it out and verify the thing, that would at least give the buyer and seller some confidence ;-)
