I use Walmart pay with their app. But then again we’ve totally given up buying off Amazon and do grocery pickup or delivery from Walmart. For 90% of items this is faster than we’d get it from Amazon.

Some of it may be that if I'm in a store, I've almost certainly driven there so I probably have my (small) wallet with me.

How often do you find yourself somewhere with your phone but not your wallet?

I always have my phone in my pocket. My billfold is stored in my car, and I do occasionally forget to put it in my pocket when going in to a store. Plus my billfold is thicker than my phone so it's less fun to store in a pocket.

I think this is very region specific. I'm in the UK and hardly ever take my wallet with me unless I'm going somewhere that I know to be cash only and might need to find a cash machine. Only other time I do take my wallet is when I'm in Germany where most places seem to dislike cards.
