The half orc and half elf are both 20 percent off this week (and next week). This means the half bloods bundle is now a grand total of 3 TP more expensive than buying the seperate races on sale.
I must honestly say I don't see much in buying seperate races for 20 % off when the normal bundle price is only 3 tp higher.
Why don't you put the half blood bundle(s) for sale too? That way one can still enjoy the sale by buying a seperate race if they bought one already, or buy the bundle(s) at a discount.
Going to bed now.
