3. The game does not round the costs. For example, Deep Injection 3 costs 1.461Sp, and you can buy it before hitting 1.47Sp as it displays. Similarly the twinkles cost 9.999x10^whatever. 4. Deep Injection 3 is too strong to be given when you expect it to, so it has the cost and unlock requirements you'd expect for #4.
