I've only just realised (after over a year of pinning my items on Pinterest) that once a listing you've pinned has expired, the link to it via Pinterest tells you that it is no longer listed/available. This means that every new repost has to be pinned back on Pinterest for the link to remain current. I expect lots of ebidders already know this, but I thought I'd mention it just in case there is anyone else out there who doesn't know.
