We just moved from a very rural area to a large city and am surprised at all the food delivery/rent-a-bike-or-scooter/ride-share/car-share/random delivery/etc. apps and services that are available. What do you find you get the most use of and most value for money?
Too Good to Go - buy restaurant surplus food for cheap
Ride share availability of any kind is light-years better in urban areas, as is public transit.
Any secondhand shopping like craigslist or Facebook marketplace will also have much better stuff.
