hello - as far as i can see, simple postage evri parcel weight increments are 1kg, 2kg, 15kg. this seems like a big jump from 2 to 15. i have things to sell that would be circa 3 to 5 kg but £7+ seems a bit excessive to send them. is there any way of suggesting to ebay that some intermediate steps, say 5kg, 10kg, might be helpful?
