Taking my existing items and opening an eBay store.Is this possible and how do I do it?

Is a store better in the long run?

would my sales improve and is it possible to just switch over easily?

 Thanks

Open a store is super easy and everything just moves to it automatically.  While there are lots of perks, it usually isn't worth it unless listing at least a 100 items or more.  The more you list and sell the more a store is worth having.
