Prices

Prices of items are as follows: Prices are multiplied by 3 for each mod, so that a red item is worth 27 times as much as a plain item. When selling to the store, you only get 10% of the sales price, and it's in credits. When buying from the store, plain and green items cost credits, and blue and red ones cost platinum. The platinum price is 1 hundredth of the credit price, and is always a multiple of 9, which will involve rounding if the blue credit price is not a multiple of 900.

The price of upgrades is the same regardless of the base price of the item, so you're better off upgrading expensive items.
