Unfortunately I wasn't able to replicate the wildcard search.... sorry.
But.....
I've got you 340 characters instead of 100! So you can use much longer and complex queries.
You can pick a category and include or exclude up to 100 sellers. You have a choice from many sorts, including a few not even available on
ebay. It will return pages and pages of results.
Here's the best part.
Build your search one time and bookmark it! You don't have to build it every time!
So check it out and report back....
