8 charges on 1 transaction?

About a day ago I purchased a few items from a few different sellers. 6 items total. The total ended up being about 187 dollars. Now I just checked my bank statements today and notice that I currently have 2 charges pending. One of the charges being a couple dollars more than the initial charge.  Then in the completed transactions I noticed I was charged for each item individually despite doing the order all at once. So I have been charged 3x for what I should have payed? Is there a reason to this? If not is there a way I can contact eBay about this?

What are the item numbers?

eBay have been known to apply charges twice until the payment clears. The additional will show as pending. Wait a few days and see if it resolves, which it usually does.
