Q: What's in the Ultimate Bundle IAP?
A: The Ultimate Bundle IAP is a way to get these things for a lower price than you'd pay to get them separately:
Q: Does the Ultimate Bundle stack with the Honey Maximizer?
A: They don't stack. There's one Honey Maximizer feature, and purchasing it either directly or through the Ultimate Bundle turns it on, but purchasing it both ways doesn't give more benefit than just purchasing it one way.
