Since a lot of players bought the 97 or 122 slot unlocked bags when they came available, and would likely have bought the 151 slot bag if it was made available at the start, I would like to suggest that you offer an upgrade price for the difference in the unlocked purchase of the infinity vs the nullity or 97 slot bag.
It likely will lead to more sales, since a lot of the dedicated players already bought a 122 or so bag and might not have enough funcom points/cash to go and buy a more expensive bag. But the same players would be much more likely to buy an upgrade on their bags if they only had to pay the difference in the unlocked prices.
I don't know if this is marketing or dev suggestion though.
