iCraftgifts home page banner question

[designsbydebra]

Hi I have noticed that the banner on the iCraftgifts home page features the same shop. I was wondering how other iCraftgifts shops could apply to have their items featured and if there is a cost involved?
Also there seems to be some empty spaces below the banner in the gifts for her and gifts for him etc. rows. How are those products picked to be featured?
Thanks
