Well, if you are an author of application, it's simple.
When purchasing is started, save state of purchasing in Preferences. Something like this
0 - start of purchasing
1 - first state
2 - second state
...
n - receipt has been got.

When Internet connection lost, the procedure of purchasing is interrupted, Preferences holds last state before lost of connection.
Your application look at the Preferences and sees that purchasing was not finished. So application knows that purchasing has been interrupted and shows relevant information on screen. When Internet connection restored, application repeats purchasing.
