This is basically what dollar stores do. You have to lose profit on some items to get traffic and regain that profit in different items. Traffic is exponentially better than being profitable in every item since you can expose the customer base to other products and start deploying other fidelization channels. You won't get that if you have the same outlier buyers giving you profit on a few expensive items.
