Yeah, it´s a problem with Daedalic games mostly.. They have big bundles for 90% off a lot of times.. so now for instance The Daedalic Armageddon Bundle is on sale for 90% off, so the current price is 15,99 (in Euro's at least) while Memoria alone is 19,99. So SG sees 15,99 as the cheapest price to get Memoria, so instead of taking the base price of Memoria itself as P value, it takes the base value of The Daedalic Armageddon Bundle (159,99). It's a bit annoying ;-)
