A seller can use "Courier" delivery method where the delivery costs are added AFTER the sale
This is usually for items larger than a regular parcel service (tons of shingle, etc)
I won a small item and seller added £12 delivery for an item that would cost £3.50 48 tracked in Royal Mail
I won an bargain for £30 in auction so the seller just added £500 delivery charge. Yeap £500!!!!!
Seller would not respond
Ebay customer service just acknowledged the delivery charge but did absolutely nothing
I got a strike as a none paying bidder and could not even feedback
One year on and that same seller is still advertising "Courier" delivery for the same scams
Be very aware if the seller is using "Courier" service when a regular parcel service could be used
