Pinn's store is a great place to get deals. It is generally a little cheaper to buy anything here than through the regular store.
This is also the only way to buy Auto tickets.
Pinn's store is notable as one of the best ways to aquire 4 star runes, usable for grade up mats in the terrible path of getting 5 star runes.
Buying a regular rune from Pinn's store has a very small chance of giving you a rare rune.
Purchasing directly from Pinn's store is one of the best ways to get rare runes.
And watch out! There is a lot of variance in the price of runes in Pinn's store. Although you may pay a premium if the rune you want comes up rather than just waiting constantly for it to come again at a better price.
