Browse offers on the app's home screen, open one that interests you, and tap to save it. That is all — the offer is now attached to your account.
You can save as many as you like, and saving one costs nothing and commits you to nothing.
An offer only pays if it was saved before you bought the product. See Why do I have to save an offer before shopping?
Your saved offers are listed together in the app, with the last date each one can be used.
