I'm about to list a bedside crib for sale and am trying to work out how much to charge for postage. It weighs 12kg. It's currently assembled but I estimate that when it's flatpacked it will be roughly 100cm 60cm 30cm. I don't have the original box. So, depending on what packaging I use it could end up being too big for Payperdrop (size limit 120x60x60cms)or Parcelforce ("must not exceed 3 metres length and girth (measured around its thickest part) combined".
So, are there any couriers with more generous size limits? Should I offer to post it and risk finding out that it's over the size limits when it's all packed up? Or should I just put it up for collection only? Presumably it'd be less likely to sell if it's collection only.
HELP!
