Ordered two items from the same seller but first put one colour of the item in the basket then continued shopping and put the second item in the basket. Then went to the checkout and requested an invoice from the seller - I wanted to ask if there might be a discount for combined postage and it was the only link on the order page that allowed me to send the seller a message. I obliged to but the items. Then I receive the invoice with a postage that is more than the two P&Ps combined together. We are talking small sums here but hello, I asked about the postage discount and now s/he wants to charge me more for that? I will say Im happy with the postage as advertised but if they refuse, am I obliged to pay more than expected?
