It looks like the feed is cutting-off the rest of the post. I would recommend putting the “buy button” above the description. By default, WordPress links back to the post on your site, but I think if you move the but button higher, it should also add that link to the RSS feed.
I have changed it but on my feed you can see something like this
<!-- END App Name -->
<!-- END App Icon -->
<!-- END Description -->
<!-- END AppStore Badge -->
<!-- END App Details -->
<!-- END GameCenter Enabled -->
<!-- END iPhone Screenshots -->
<!-- END iPad Screenshots -->
<!-- END Supported Devices -->
<!-- END AppStore Buy Button -->
<!-- END App Store Rating -->
