Simple mail overcharging

[lordluca93]

When I sell 2 or 3 of my time tona buyer Ebay charges extortionate postage fees. The postage should be the same price for a 3 items as it is for a single item. The weight per item is 320f, so 3 is under 1kg and still large letter. I cant find anywhere to add the weight of my item. I find it disgraceful that eBay do this and no help is available to resolve this. I have to use Royal Mail due to my location. Can someone advise please?

You are trading from a private account.

Change to a business account: you won't have to use Simple Delivery and will be able to combine postage on orders from your buyers at your discretion.

If you do freepost, you can't combine postage.

As said, you need to upgrade to business seller.
