Apologies if this has been mentioned before - I found a similar thread about BIN sales, but my request is a bit different.
I sell photos and many times a buyer will bid on two or more pictures (separate auctions). All my auctions state that ALL wins will be posted together for a single P&P fee.
But when I prepare the invoice I find the select postage discount mechanism clumsy and error prone. I have to do my own sums to work out a discount of n-1 postage charges and be very careful to select £ discount rather than %.
Am I missing an easy method?
Is there any way to automate - "all items for a single P&P charge" (pick the highest if charges differ between won items) ???
As I have never bought multiple items here - I don't know what options a buyer gets when he "Pays" - is (s)he allowed to combine postage??
(business picking up slowly - so an improvement here will be a great advantage when it starts to BOOM)
