Never end up with less than 2%. But, like anything in life, we all have different hobbies. This one not worth it to you.
My wife and I by using credit cards received over $2000 in cash back from banks last year, that makes it a fun thing for us even though we are kind of out of things to buy anymore.
Crap I even have a Maui Jim Sunglass collection paid for by them and even though Im not a fan of Costa they had a nice frame/lens color combination that I just bought two weeks ago. I tried to custom order a similar item from Maui Jim but supply issue on the frames.

Gosh, throw in two Mac computers ... ear buds... ya da ya da ... its just a fun thing for us. Some people bet on sports teams, some lottery tickets, others whatever, we do the sure thing and have banks give us the money for free.
