Most Ebid customers come in from Google, the more individual items that you have listed the better your chances of being picked up in searches.
Free shipping is not popular on Ebid, people prefer to get discounts on shipping when purchasing multiple items, (this also might encourage people to purchase more than one item), also a US customer would probably expect to pay less for one of your items including shipping, than a customer in Europe, which is another reason free shipping isn't popular.
Gallery pictures are popular on Ebid, many people just skip anything without a picture, your multi item listing has one gallery picture for 26 different items.
If I searched for any of those 26 items by name in the title they would not appear.
This multi item format of listing is making it much harder for people to find your stuff, and I expect in most cases they won't.
So my advice is create 26 different listings each with a gallery picture, unique title and at least a Buy It Now price so that they get picked up in Google.
