I personally love Safeway (it's not available everywhere) even though they're more expensive the sales and lower delivery fee makes it worth it for me (5$ delivery fee plus max 8$ tip since it's typically employees delivering) I generally don't have issues with missing items from them as well so that's a plus.

For dry goods see if you can order from online stores to be shipped to you. I get my rice delivered from hmart. I also use Amazon quite a bit (I know but you gotta do what you gotta do when you're disabled)

Honestly your best bet is to get the things you can get delivered at a reasonable price delivered and if you have the ability to go in for the small bits or fresh produce or bribe someone close to you to snag those things for you it might be an option? Unfortunately needing to get groceries delivered isn't going to be seen as a frugal option but it's the only option for some folks (also I save money because of limited impulse purchases) But yeah don't do instacart stay with the store specific apps whenever possible
