the few items i sold on e bay i allways lost out on postage because i forgot to (a) weigh the item with the packaging and (b) take the cost of the packaging into account, one item i sold was a babys playmatit sold for 99p i charged £1 for posting because off its size i had to buy a huge padded envelope that was £1.50 then at post office it cost me nearly £3 i gave up after that, some sellers do take the mick though i have recieved items packed in a black bin liner, reused envelopes. last week i gave two fiskars texture boards to a group member and used a used padded envelope reason being to keep my cost down as i wasnt selling them but if i had been i would have used new ones. i gave up selling on e bay
