thesoulyearns,

re using ebays Calculated Post tool

IF it is going as a SOFT PARCEL all you need [until these new changes come in re cubing EVERyTHING] to enter is any number ... I put 5 x 5 x 5 at the moment.

What you do have to remember with a soft parcel [that is NOT BOXED] is how much protection weight is going to be added to the actual item.. e.g. item weighs 220 grams + packaging 150 grams = 410 grams .. you simply put 500 grams - nearest package for AP weight [or 410 grams] in the weight box.

If it is going to be BOXED that is different.

Find the correct box you will be packing item in.

Add protection & item to box

Weigh the lot

Measure the box

Add those exact measurements e.g 24 x 23 x 22 ... to measurements boxes.

Then add exact weight as the calculator will round it to nearest match

Also consider [if it will fit] adding either the 3kg or 5kg satchel if you can safely package the item boxed into the satchel....this way you DON'T get charged for BOX postage.

Hope this helps
