With the release of Transmit iOS and Prompt 2, we excitedly added two Panic Pack bundles to the App Store. Bundles are a great chance to reward loyal customers a little bit of a discount on our software — something that was not possible to do on the App Store previously.

Even better, customers can “Complete My Bundle” — if they’ve bought any of our apps, they can pay the difference to receive additional missing apps at a discount.

But once our bundles hit the App Store, some curious “Complete My Bundle” questions began to roll in. Pricing seemed to be weird or inconsistent. So we did a little digging and got some good tips on Twitter.

Panic just solved the mystery of obscure Complete My Bundle pricing. It makes sense after reading their conclusion, and it confirms that bundles won’t always be the most convenient option.
