Two things, I suspect you sent the item on the simple delivery, which means if the item was not received and or was damaged in transit ebay will cover the cost to the buyer, you already have the money so check your payments tabe to ensure that you do still have the monies.
Secondly you are selling new and multiple new items, private sellers don't have this sort of things stuffed away in their garage or cupboards if they are a genuine private seller. I suspect you need to upgrade your account correctly to a business seller.
