Check if the sellers are ‘prime eligible’. Not all of them deliver in 2 days. There is a small list of exception. I wanted to buy a product which said 14-20 days for delivery. I ordered using my friend’s Prime account and it still took the same amount of time.
It’s also a huge waste of water but your City or HOA will force you to mow it. I share the same sentiment as you and would be happy to use the land for anything apart from just a green lawn which needs to be mowed.
