Why don't people list all (or even most) of their items in one ad? I have spoken for an item just to see the same person has other items I can use listed later after I've already paid. I avoid those repeat sales because I'd pay shipping twice. If items were in one ad the person could sell in bundles, ship fewer packages, and manage their sales easier.
Dinny, you post the way you want to post, and ALL the other Guys will post the WAY they want to post.
