I really can't see there being more than 2 items per shop at best. 3 per sho would give 3X more possible items per run and then you might as well scrape the item locker as a concept

I still sort of feel like 3 regular, 2 with 2 items and one "mall" (3,4 items?) sounds bets to me, allthough everyone'd be scumming for the mall, the greedy powergamers that we all are...
