charged twice for shipping

[halfgweilo]

I recently bought 2 sets of stamps, same set and same time. At the end of my purchase my receipt show I been charged twice for shipping cost. Seller adveritised he had 4 sets available, because I wanted 2 sets I clicked 2 in the little box. I contacted seller seeking reason for same. He advice that was because I bought 2 sets. He said he would refund one shipping cost but will minus eBay's commission as this has already taken out. I asked seller if I had bought 4 sets would the shipping cost be times 4 then? He didn't reply. One would believe the sysytem, can recognise, regardless on the numbers of sets I bought, it would still be one transaction and only one shipping cost should  be charged.

It sounds like your seller is in the USA.....he is probably using the GSP and has no control over the postage being charged for that service.

The seller only sends the items to the GSP facility who then send them overseas.  No matter what the seller wants to do, the GSP does NOT allow for combined postage.....you always pay full postage on every item even if they are combined in one package.

If you are buying stamps using the GSP you are probably paying through the nose and it is not the seller's fault.  The system is not meant for envelopes....it is supposed to be for parcels.  The larger the parcel the more economical the GSP becomes.
