That was pretty much what I found while I was using grocery delivery (Peapod) because I was on crutches. This was a while back and there are generally more options today (though not where I live fr the most part). I'd get substitutions I didn't care for and random common items I absolutely needed for a recipe would be out of stock.

I could imagine using a reliable service again but, so long as driving to the store and shopping is straightforward, ordering online for delivery isn't something I really need.
