Supermarkets loose money if goods do not sell, storage is expensive and limited shelf space , will also promote your product visibility or even give exclusivity etc . Apple takes no risk and does none of the above, so not remotely the same. Sure if Apple is willing to buy apps from Epic in bulk and speculate in addition to distribute, Epic or any other dev is not going to say no. Fulfilled by Amazon is much better comparison, you get paid only if the customer actually buys, you get penalized for returns etc. Providing the market place, the customer, the delivery service, storage service and payment gateway. Amazon does not charge even close to 30% in most SKUs.
