It will probably be a relatively opaque increase in cost. A lot of the cost of using IC/Shipt/etc. is actually in the cost of the products rather than in the delivery fee. Each service has its _own_ cost for each product (in fact, as a shopper it is suggested to download the customer app so you can answer questions about prices).
True "delivery fees" are only enacted for non-subscriber or small orders.
