Saw this when someone was making a Cart for the Store, and taking this idea and putting it into perspective. as with the current store layout, a full cart isn't needed, but this idea was. You know who you are. [ WIP ]
This addition will be able to let users see how many xats they're spending in case they're buying in bulk, and don't want to have to pull out a calculator to do the math.
I feel for any store, a Total cost of product should be displayed somewhere, and with the new re model of the store, it only makes sense to add such a helpful tool to calculate the entire purchase inside the store.
