Maybe it's a white lie, but saying they sell 250 would be just a lie.

It's almost 60 games, while you only need to buy 20 packs. Why should they ignore that?

You forgot Lords of the Realm Royal Edition which includes Lords of the Realm I+II and the Siege Expansion for II.

I would question it - why it's only 250 while they are selling almost 300 ;)

There are 29 products with compilation/pack/+ in their title. So:

EDIT: Ignore that bit, it also counts things with "+ Expansion" >.< Doh!

255 - 20 = 235
235 + 60 = 295

So now the question is.. which 5 games aren't going to be in the sale?! :P

Thanks for the extra help/information everyone :)
