Help - does anyone know how postage costs for additional items is calculated?
I currently send my scarves wrapped in a cellophane bag in a poly bag envelope but want to add the option of having them gift wrapped in a box. My smaller scarves currently ship as large letter size and larger ones slip into the small parcel bracket, I send them first class signed for and charge £2.50 and £4.50 respectively.
If I add a gift box both will have to go small parcel at £4.50.
So my question is this. If I list my smaller scarves with a postage of £2.50 and £2 for additional items and the larger ones at £4.50 and £0 for additional items and then list the boxes with a postal rate of £0 will this come out at £4.50 for both if ordered with a box?
My problem then comes if someone orders a box on its own - if I put a postal rate of £2.50 with £0 for additional items on the box listing will that result in the following
small scarf alone £2.50
large scarf alone £4.50
small scarf with box £4.50
large scarf with box £4.50
box alone £2.50
Trying to get my head round it all! Thanks in advance.
