I strangely can't find a single search result on the forums about this. I know I could tentatively use paypal HTML in an app on android, and perhaps iOS if I added it after I uploaded. How would one go about actually adding in-app purchases though? Example: Restaurant that wants to let people order food for delivery or pickup using an encrypted form. Selling items like a virtual pawn shop. Etc. How would one go about that through Terms-of-Use/Agreement-legal ways, if possible?

oops, found 3 of them now. Still no definitive answers though...

What about using something like groupon or kgb javascript widgets, depending on how much you can fine tune them? That way you earn an affiliate commission and you pass on the stress and hassle of transaction management to the third party. It would work for your restaurant example, not sure about the pawn shop though.

neither are allowed under app store terms of service :/

No way! Switch to Android!

lol I know, just I want to make it available on both. I already have a Nexus S ;)

Is it just Groupon and KGB or is it every group buying site that's not allowed? Could you get around it by using an aggregator? In your blurb you say something about 'constantly scanning the internet to bring the best deals from all the daily deals sites into one useful app blah blah blah'? There are a number of aggregator solutions around the net, eg sqoot.

yes, but apple terms and conditions say the rules are you have to go through its own in-app purchasing method, where I'm sure apple takes like, a 30% cut or something. There's always the option of adding it post-upload, but there's no for sure way to tell if it would work as I don't know how often apple rescans an app to make sure it's playing by their rules

Ah, I see. Apple squeezing every last cent they can!

Ah, I see. Apple squeezing every last cent they possibly can!

not sure... can't you buy things from amazon through app? must be a way
