Hi there. I'm 41 and from Cornwall. I've been a keen e-bayer for a number of years now. I always aim to post out items as soon as possible after the end of a sale (this is of course once payment has been received) :)
P&P charges are always cleary marked with each item for sale. Of course, if a buyer is making several purchases of items due to close at the same time; then I would be happy to amend postage to reflect the difference.
