How do I add in-app purchases in my mobile apps developed with Flash CS6?

[ArithmeQuick]

Using Flash CS6, I have developed a free app, Now I would like to give the user the opportunity to purchase something more while using the free app.

develop your own native exension or, buy milkman's: Tools « Milkman Games

I see that Milkman has the following two extensions for sale @ $49.99 each:
(1) In-app Billing Android Extension
(2) In-app Purchase iOS Extension

In (1), When I click on 3 of the 4 links listed under 'See it in action', I get:  "We're sorry, the requested URL was not found on this server."

In (2), When I click on 2 of the 7 links listed under 'See it in action', I get:  "The item you requested is not currently available in the U.S. store."

Should it concern me as to why 5 of 11 items have been removed?

i've never had a problem with milkman's extensions and i own 5 of his extensions including the ios in-app purchase.

well, actually i have had problems but he (alex liebert) has always been helpful and it's always been my error or a need for an updated version that he promptly provides.

my guess is those links have changed because the creaters uploaded updated versions.  you could search for the apps (in google play and apple app store) and ask the creators if they've had a problem.
