OK. I'll bite.
For those of you who are members of Amazon Prime: What sort of things do you buy for which the two day delivery is important? Otherwise you would get in the car and drive to the store if the wait was more than two days.
To me Amazon prime is not just the 2 day delivery. There are other factors.
That said, in many cases, the 2 day delivery is not "important" but it is nice and convenient and I like it. And, it is worth $99 a year
to me to get it. 2 day delivery is sort of a sweet spot where if there is something that I want now (but don't have to absolutely have right now), I'm willing to give up getting now if I get in return (1) lower price on Amazon, (2) don't have to drive to and from the store and shop - an hour and a half total at minimum usually closer to 2 hours, and (3) I get it within 2 days. If I won't get the item for a longer period of time, the tipping point is more likely to tip to getting in the car and going and finding it unless the price discount for buying at Amazon is significant.
Anyway, examples:
Dragon Ice Relief & Recovery Balm - Just ordered this today for current use. We actually
did stop at a store for this but the store that was supposed to have it didn't have it. The other store nearby that has it is in the mall and it is sort of a pain to get to and I couldn't do it until tomorrow anyway. Since this is for current use (want to use this now), I would not want to wait for a long delivery.
Logitech Keyboard cover Mini for Ipad - DH's ipad keyboard cover broke. He uses it a lot and the price was better at Amazon. He could have done without it, of course, but he didn't mind waiting 2 days to get it from Amazon instead of going to store. He would not have wanted to wait several days.
Textbooks - I bought all my daughter's textbooks online from Amazon for this semester. Getting quick delivery was essential to ordering them. If I had not had Amazon Prime I would have paid for 2 day delivery.
Olloclip 4-in-1 - This was a Christmas present from DH to me and didn't arrive for Christmas as part of the whole UPS snafu. The 2 day shipping was important since it was intended to be a gift to be here on Christmas (no DH couldn't have bought it earlier as he didn't know earlier that I wanted it). The present I bought him from Amazon did arrive within the 2 days.
Meat Thermometer - 2 day shipping wasn't crucial, but was a nice to have.
Shredder - Far cheaper to buy from Amazon than other options. Our shredder died abruptly so we didn't foresee the need to replace this. Again, the 2 day shipping wasn't crucial as the price was so good I would have waiting for a longer delivery if necessary. However, we had no shredder until this one arrived so it was nice to have the 2 day delivery.
New mouse/keyboard - Price was very good so I probably would have waited even for a longer delivery time. But, the 2 day delivery was nice and much preferable since my keyboard had broken and I needed a new one ASAP (I was using an old one we had laying around but it didn't have the features I like).
Elf Ears - My son was making a costume for an event and it is actually not that easy to find elf ears. The 2 day shipping was very convenient when he found that out.
Roomba - The price was the same online as going to the store. It was just more convenient to do it online since I was getting 2 day shipping. Without the 2 day shipping we probably would have made the trip to the store to buy it (about 2 hour turnaround).
I could list lots of things, but the general statements would be largely the same. I usually get a better price at Amazon and it is convenient to get 2 day shipping. Sometimes, it has been more important than other times. A lot of the time it is simply a "nice to have."
