When I was a kid, there used to be plenty of shops and the online magazines which used to offer the rewards for using their services. And those point collection collectively used to get the rewards too. So now the same concept is not dead yet. Many blockchains, reward companies and the apps collectively offers such. In case of the bitcoin and lightning network you have an app called sMiles.

sMiles app and the browser extension has been going on good with their activity and rewards combo. And the way rewards are working I feel a lot of nostr usres and the lightning network users would find this one useful.

I like the way they reward you for doing some tasks, using their apps for payment and also using it for variety of places like desktop, mobile etc. And collectively this would get benefit for both side. though how much those rewards would be useful depends on your financial condition too as some rewards hardly make sense for some as they would ignore that. 

So if you are one of those thrifty and want to earn the rewards and even earn the satoshis back considering this is more or less cashback you can see that it would definitely make sense and in a grand scheme of things this would benefit for your whole experience for shopping too.
