Usually I don't bother checking for stock when the price seems too low, as always out of stock, but not today!
Collected from Manchester - Fort (Cheetham Hill) today and it's not the platinum version.
The Comet site does show The Sims2 Pets cover but that's just an error before you get exited.
They had more on the shelves priced at £9.99 but scanned at £4.99. NOTE* The guy who served me said "We get this all the time, some bloke came up before with a XBox 360 Game and handed me £45 but when I scanned it, it came up as £4.99 !"
If your fortunate enough to bag a bargain, great, if not, it's only taken a few clicks (or words, if you ask in shop) to find out.
