We have a thing called GoPuff where I live. It's a delivery service like Door Dash or InstaCart but they only deliver snacks, drinks, frozen food, and basic household stuff.
The internal debate I always have about using them is that I really just want one snack but you have to order at least $12 worth of stuff or else they charge a "small order fee" where you basically pay the same amount anyway.
I know once all of those snacks are there in front of me I'll end up eating them all and get a stomach ache, but I also really don't want to get dressed and go all the way back to the store again...
15 minutes? I've never used any delivery app where they had to be there in 15 minutes! Usually the "estimated delivery time" is like 45 minutes but there's no official set time they have to beat. They all seem to kind of take their time honestly lol
There's such a company in Amsterdam that promises to get it to you in under 15 minutes, but you don't see them that much any more, at least I haven't in the past year or so. I think they've been regulated out of the market. It's rare you can't do your own shopping more quickly, too.
Postmates is kinda the same but it's not limited to anything; they just go wherever and grab whatever for you and bring it to you. You can get snacks, meals, even cigarettes and alcohol. I've only ever been a delivery person through 'em though. Never actually utilized the service myself lol
It wouldn't surprise me if their range of availability hasn't changed. It was pretty small. I stopped doing it because it only had a range of like 5 miles where I would be visible to people ordering. Didn't feel like I was getting as much as I could if the range was further away considering I have a car and wasn't doing things on foot/bike.
