If you're looking for your family's medals, a collector is selling a whole load on eBay at the moment.
EBay's generally worth following for medals, of course, but this looks like a particularly large haul.

It includes WWI and WWII, and some Boer War (King's South Africa Medal). There are WWII Africa service medals troops (surnames include Kgasi, Masetsho and Mondhlane) and at least one medal awarded to Canadian troops, so it's a fair old spread.
I'm not connected with this seller, BTW. I've just managed to get hold of some of my relative's awards through eBay, so wanted to share!
