Combining postage

[WelshMoth]

A buyer has bought 4 items of
Children's clothes for me. Each item was £2.90 p&p. How much should I charge for a combined postage do you think?

Whatever the cost is for the next size package up, I reckon.
You can look it up on the mail website, I think.

Thanks! Will have a good look. I use the app - any ideas how I adjust the combined price of all items and p&p?

You can send them an invoice via PayPal for the total amount plus the adjusted postage.

If it's just light clothing it'll probably only cost £2.90 to send all 4 together

Just in case anyone doesn't know the Royal Mail small parcel price for 2nd class has just gone up to £3.00. Also eBay have started charging their 10% fee on postage as well as the selling price so I always add 10% onto Royal Mail price usually plus about 15p to cover mailing bags, jiffy bags etc.

Thanks everyone - you've all given helpful advice. Can this adjustment be made on the PayPal App?
