Combining Postage

[chloesmumtoo]

Just a quick check before I start selling on ebay again incase anything has changed. Usually when I sell I add a message telling buyers that I will combine postage and that they can add items to basket and then request total/invoice from me and I will ammend postage. Having had a buyer struggle with this last time I just wondered has anything changed on ebay checkout/basket and is this the correct proceedure to tell buyers? Is it the same for buy it now and auction? I dont want to give the wrong instructions on listings. Thanks
