Sort by price per use

Currently in both item and credit sales everything is listed in order of price, from cheapest to most expensive. Could we get a Price Per Use added to item sales (credit sales already have Price Per Credit) and also have the optional ability to order everything by price per item instead of total price?

Could not support this more! I'd particularly like it for buying treats in item sales. Both for buying (I don't 100% trust my brain to always do the math right to discern a bargain and a scam) and for selling - listing a compressed stack of yellow apples for 40k looks weird until you see that relative to the number of items it's a big discount compared to the store. 

yes yes yes!!! Sometimes it seems like a  great deal at first, then... it isn't :P
