Items are marked as unavailable because the shoppers can't be bothered to look for them or provide a substitute. Go to the store and items are definitely in stock. The last straw for me was the last 3 orders I placed never came due to lack of available drivers. When I cancel the order it takes over a week for the charge to stop pending so I've had to go without. So inconvenient. I'll pay more for Instacart because at least then I'll get what I order.
