Never use DHL as a shipping option when shopping online

I've been caught once, by receiving a package that was shipped from overseas, where the delivery worker arrived with a package and an acquisition fee for more than what the item was worth.

I looked into fighting it, but found out that the fee was not customs at the border, but the processing and transaction fee charged by DHL. Their FAQ is of no help.

Above shown is an invoice that was presented to me with the delivery of the package. The item is worth  $27. I paid the shipper $17 for shipping which I thought was reasonable. However when DHL delivered the item, they were collecting $3.48 for import tax, which I found fair, but collecting a processing and transaction fee of more than $14.

End of story. Never use DHL.
