>>127120I don't order groceries online, but this isn't true at all from my experience. I live close to the store so I just do the few minutes walk at non-peak hours, but I have tried it a fair bit.
If your groceries are at risk of being stolen, you live in a bad neighbourhood. That's the real problem. You don't have to use an app, there's a simple shopping website online. You can schedule the delivery time period and choose between delivery at door (ring doorbell, not allowing it to be set at doorstep if you're not home), or delivery at doorstep (ideal for hikis to take inside a few minutes after delivery man leaves).
The store is very good at displaying what's in stock and ready to deliver today/tomorrow or what will cause there to be a delivery delay.
I never had a bad experience with the service I used anyways, but I do live in a small country. It's not particularly expensive either, but I prefer just going to the store than planning ahead. It's a good service to have though, I used it a lot during 2020.
