Don't know if you guys guys have heard of this before, but now you can print your postage online (without charge - unlike smartstamp).
I've done it a few times now, you can even print onto a blank sheet of paper and sellotape it to your letter if you don't have any suitable labels.
Beats having to bear the sour faced witches at the Post Office :evil:
Shame I'll have to go in 2moro to get a recorded slip stamped (I printed off the postage online), but that should only take 10 seconds!
Great for my ebaying :)
