1. Most are clearly used and low demand items to begin with.
2. It's summer. Fewer bidders online.
3. The seller does nothing to "talk up" the items.
Just because something is listed doesn't mean it's ever going to sell. I've seen some sellers relist the same item a dozen times with no sale.
The mens shirt should have had the tickets as the primary sale item instead of the shirt. In fact it should not have included the other stuff at all. I don't even see the size of the shirt listed.
Items that are not in high demand need to be made desirable. A talented seller can do this. The photos are few and mostly poor. The general descriptions are boring. I've been selling on eBay for close to 17 years now. If I had written those listings I would have been out of business 16 1/2 years ago.
Find someone else to sell for you. I once boasted that I could sell anything that was legal to sell. Even I wouldn't bother with most of those items; and I once sold an old sock with some holes in it.
All these items no one wants. They all looked used and have almost zero demand. Clothing are hard to sell unless it's a brand name. I wouldn't bother with trying to sell most of this stuff. The fees and the time is not even worth your trouble.
He's not doing anything wrong.. Their using good strategy by listing it for a penny & jacking up the shipping price which may hurt his DSR rating later.
The items aren't high demand products so it'll take many auction rounds for the stuff to sell. If you want them to sell quicker, you can bundle up items that are related. If you have multiple clothing items, put them in a bundle/lot, etc.
Ok, so what you need to do is tell us what the problem is.
Hope this helps
