Need help with permalinks wordpress

I am building a webshop, I want to add my items like this
domain.com/store/items----> Put items here
domain.com/store/related items----> related items here
domain.com/store/other related items----> items here

I now have domain.com/category/store and then my items are here. How do I change this with permalinks? I don't really understand this and I searched in google but couldn't find what I was looking for.

I am using wordpress

with items I mean for example:


store/dogs ( dogs are here )
store/dog cages ( dog cages are here )

Thanks in advance .

Try this:

1) Set your permalinks to /%category%/%postname%/ in WordPress settings,
2) Create a category called "store" in your posts section,
3) Now for each post, edit the permalink at the top of your post to be what you want (avoid using spaces!)
4) And make sure you include the post in the category "store".

I hope that makes sense. It should work.
