Notes

I don't know what the free subscription periods for Audm and FarFaria are, as I didn't sign up to them. Let me know if you do, and I'll update the post. Edit: Updated FarFaria to 6 months.

I didn't tag this as a 'Freebie', as charges will be incurred should one not cancel their Scribd trial subscription, i.e. there are "strings attached". Edit: I’ve, now, tagged this post as 'Freebie', as it may be a long running deal. Please, report to the Mods should the deal change or expire.

Apps, except Audm (iOS only), for the above services are available for iOS and Android.
