There's some information that could be added to the Backgrounds page if you wish. From the Newbies guild:

Chimeric asked:

Backgrounds are 7 gems each or 15 for a set of 3. If I've already unlocked one background and then decide I want the rest of the set, does the system "remember" that I spent 7 gems and only deduct 8 more? Or does it still deduct the full 15? (in which case it makes more sense to buy the other two individually)

I replied:

If you buy one background, and then click on the "buy the set for 15 gems" option, that option will still cost 15 gems (I've just tested to confirm this). So as you say, you should buy the remaining two backgrounds individually.

Rewrite as you see fit.
