Hello. IVe just purchased an item and the courier company selected by the seller is not one that I can rely upon. I've asked the seller to sent it through with Royal Mail as opposed to both offered options Yodel and Evri. There is a £4 price difference which I'd like to pay to the seller . Would you know how to do this ? I haven't paid for the item yet as I hope there is an option for me to increase the purchasing price by £4 to cover the additional cost of using a different courier. By the way there seem to be a click and collect option for the original postage costs but I'm not sure how to proceed. Looks like I have multiple choices Argos, Mace, Corner Shop, but I'm not sure if I can opt for that option nor am I sure the seller is willing to accommodate the request. Your help is appreciated
