The codes are not the most important aspect of the guide. What's important is that it explains you how to coin farm, how to get lives, what not to spend crystals on, etc. etc. etc.

The coupons are just an extra anyway and won't help you on the long run anyway. The other tips are (for beginners) imo more valuable than the coupons.
