eBay charges extra for its store.
The Collecting Fun store comes at no extra charge.

eBay store items barely show up in searches. Auction items are given much higher priority. You need to do a separate search for store items. Many people don't bother.
Collecting Fun store items and the search list items are one and the same. Any item in a seller's inventory shows up under both.

eBay categorizes stores in many categories, based on what they may be selling, not what they actually are. So when you go to slot cards, you can find stores that deal with Tupperware or casino pins only.
Collecting Fun has exactly the same structure under stores that it has for its main page. So when you go to a store for chips, that is the category you search. In the future, we will also let store owners customize their stores.

eBay does not provide personal assistance to its customers.
Collecting Fun does, and with pleasure.

Uploading an item for listing at Collecting Fun takes much less time than it takes on eBay. That translates into thousands of minutes over a month for intensive sellers.

eBay is a flea market. You have to look hard to separate the wheat from the chaff.
