For future reference, say if 5 games were on sale from a company for 50%(30% if buying separate) if I have one of the 5 games already would I be able to get the rest for 50% off or am I forced to buy separately for 30% off?

thanks

You can easily see the prices changing once you tick off one of the checkmarks, so you know what the games cost when you get the full discount or just the 30% one. Sometimes it's more expensive to get some of the games instead of the whole lot, other times ticking off a few games save you just a couple of pennies.

Games you own will be marked grey and included in the whole discount pack, like GameRager says.

You will get full discount if you buy all remaining games. In your example, if you have one of the five games that are on weekend sale, you have to buy all 4 remaining games to get full discount.

Thanks for the info, and will mark as question in future thanks
