I have just sold a camera on ebay and the simple delivery says its covers under royal mail small parcel
The courier will accept your package and there will be no extra charges as long as it doesn’t exceed 2.00 kg and 45 x 35 x 16 cm
the parcel i need to send is 30x23x21cm 1.8kg (which is over the small parcels limited) (its medium parcel size due to the 21cm instead of 16cm
Then on the pre-paid help part below, it says =
If your parcel exceeds the size and weight of the label, and you listed following our recommendations for the size and weight of your item, you will not be responsible for any surcharge for under declaring.
So going by this is it still ok to send it using its the label provided and i won't get charge any postage fees for oversize ??
