Great post by our friends at Mobile Orchard:
Providing a “Gift This App” mechanism would open up a universe of novel marketing, bundling and promotional opportunities — all of which would drive App Store revenues, none of which would threaten Apple’s commission. Taking a page from Amazon and providing a simple API would further support this. Lifehacker could hand pick the best personal productivity apps, negotiate a pay-per-sale arrangement with the authors, and then sell them in a bundle with a single purchase right from their site. TUAW might make a bundle — literally — of apps you can’t live without. It’s nearly Halloween; sell seasonal bundles.
