classified ad (they suck)
or put it on a cd and mail it.
use a service like kunaki (search it) if you are from a non 1st world country.
Yes . . . On CD / DVD is the way to go.
There are those on eBay who claim delivery via CD, but then email the digital product. My guess is they will be banned just as soon as eBay discovers what they are doing.
There are a few vendors who make no mention of CD / DVD and usually they forward a download location when you win the item. This also will be stopped by eBay just as soon as they discover this method.
I just (recently) purchased a DVD ckock full of Digital Information Products on Buy It Now . . . and eBay pulled the auction the very next day.
I got my goodies, the vendor sent me an email to a download location site where I discovered a shipload (About 17 to 20GB) of stuff.
The thought of uploading some of this stuff hear in the forum crossed my mind, but then I remembered the snide and ungrateful comments that many forum members make about uploads and promptly decided against it.
I can never seem to come to terms with folk who think they can outsmart a giant International organisation such as eBay on a regular basis and get away with it.
If you are interested in selling Digital Information products, eBooks, Software, and such on eBay then be ready to deliver on CD / DVD.
Be seeing you.
