I am selling some clothes on ebay and obviously want to try and keep postage costs as low as possible.
Sometimes, the clothes are hard to work out because the thickness will depend on whether you squeeze the parcel so it's at it's flattest.
So for example, I'll pack an item of clothing and left like that, it measures just over 2.5cm (so not able to send as large letter). However, if I squeeze all the air out of the bag and make the parcel as flat as possible, it will be well under 2.5cm. But ultimately, it'll fit through the letter box.
Anyone have any experience of sending as large letter and then the buyer incurring extra postage costs (which you then obviously have to cough up!)
