I wouldn't dream of selling a Mac App in the App Store. The only reason I would sell an iOS App in the App Store is that users would otherwise need to jailbreak their phones.
If someone recommends an app store product, they'll link to apple's website.
If I sell products from my own site, and someone recommends it then they'll link to my site.
In general, inbound links are worth a lot more than individual product sales.
