Next day Ingot pack ... 2 x price, but more than 2 x contents.
You're probably going to want at least 3 ingot packs during your game play lifetime.
[Handy for Perfectionist achievement, even. ]
First pack below purchased as first of that eventuality - bottom pack offered the next day. Probably worth it. 50% more RSS, 2 x Silver, (no change in boosts or errands), otherwise consistent as to contents per $.
