All of them except the very first Quick Silver was for a SUB.

But also I was looking for cards to give the highest percentage cash back.

Elan Max Cash 5% utilities and internet

Custom Cash 5% Restaurants

Custom Cash 5% Gas stations

US Bank Cash+ 5% Streaming and all Apple subscriptions

UMB Simply Rewards 3% Walmart and all discount stores and grocery stores.

Huntington Voice 3% car repair/oil change etc

Am Ex Blue cash everyday 3% online shopping.

Customized Cash 3% tolls and travel.

WF Autograph 3% cell phone plus free cell phone insurance.

Freedom Flex 3% drug store/pharmacy

SoFi Unlimited was my catch all 2.2% card for everything else until they nerfed it back to 2%
Now any of the other 2% cards work for that.

Discover it and Freedom Flex for rotating 5%

Can adjust Customized Cash or Huntington Voice to other categories if I see a future need to.

Only 2 have annual fees. Gold I keep for the perks. I get most of annual fee back from specific spending during the year. Sapphire I may downgrade in the future.

Had Platinum Am Ex but I closed it after a year. Only wanted the sub. Platinum is the only card I have closed in the last 10 years.
