Final price for combined items im selling

[gkkkpkak0agh]

I'm trying to organize a final sell price for a couple of items im selling. The 2 x items im selling have free postage, im trying to adjust the price a little to provide the buyer with a small discount for purchasing multiple items, however, the system will not let me do this. any suggestions????

If they haven't paid: send a revised invoice

If they've paid send a refund

If they are 'free' postage you cannot discount. Refund them after payment. You will be credited all relevant portions of the fees.
