I've used both Instacart and Walmart delivery because I don't have a car and live ~3miles from the nearest supermarket.

In my experience, Instacart has worked very well: the only issues (2-hour delivery window, tip for delivery) are upfront, but I rarely get messed up / late / bad orders. The website is also great.

The only time I used Walmart, my delivery was rescheduled to the next day, something which never happened with 50+ Instacart deliveries. And the website sucks.

That probably comes down to location and competence+availability of staff. I've had basically equal results from the three different grocery stores I've ordered from in my current location, one of which is Walmart, one is a Kroger subsidiary, and one is a local higher-end chain. But when I was in SF, I had terrible results with Instacart, and resorted to shopping in person.

Honestly I still wish I could shop in person, it's just too far :)

Not trying to be rude but maybe you didn't tip enough? The default tip is 5% but I usually do ~20%.

I usually tipped delivery services 15-20%, more if it was raining, but shouldn't tips be hidden and only given in aggregate? Also I wish a fair wage was just baked into the price and tipping went away.
