Thanks guys I will pass on all the helpfull info yep she new she could cancel pids relist with correct postage but she does not like to cancel bids when she as made the mistake. I would fell the same lucky its only one listing. Just really wanted to know if they provided any grace & you have answerd that. I knew 100g is wishfull thinking but it costs nothing to ask the question. Plus looks unproffessional if seller sends something with not enough postage on it not that I'm sure it wouldn't effect receiver. As click & send has contact details of sender.

Oops sorry my mistake auction has 8 days to go not 80 lol. If I had any 3kg click & send bags she could have one of mine. Either way she will order some if she does not get before listing ends in my experience she should or should that be could lol. Worst comes to worst buy a more expensive single prepaid bag at PO.
