I think that's where the 'churning' comes in. Closing and reopening some cards and moving on to different cards with nice bonuses.
Not all of us do that, even though we sort of use the term churning, we are not true churners. I rarely have closed a card. And in the last 2 years I've only opened 2 cards. Some are real churners and get many cards. No judgement here. If you read Reddit you may get judgemental as some of that is over the top.
I am partial to collecting Amex MR's and doing Amex offers as well as Chase and Bank of America offers that give cash back 5%, 10% or even 20% for purchasing at a particular store. I watch for nice earning bonuses such as a $100 statement credit for spending a $1000 on one of my Amex cards in the last year.
Almost all of what would be 1 % spend on most cards goes on my 2% card. I do look for the highest value as I spend and I will pay a fee to pay my electric bill so as to earn points on the spend. For instance I will put $600 on the bill that costs $1.95 to process, while earning $12 - $1.95, thereby earning $10.05 for paying the utility. $600 is about 1/4 of my yearly electric costs.
I will open a new card to get a bonus when I have the time before a large expense, such as the $8300 HVAC system. Got 80K for opening the CSP. One purchase. Then the CSP has had a few offers I've used just this past week, earning 10% back on a Disney card of $190 - $19 was the max return.
It all adds up. The CIC gives 5% at office stores such as Staples. I'll buy gift cards and use them elsewhere for groceries, earning 5%.
So most trips are flight, hotel, food and incidentals. Depending on where you go, collecting hotel point bonuses are fairly easy. Airline points - easy. Much of the rest, cash back. Disney used to be in this mix through various portals but they've pretty much pulled back. But, there are other choices. And, if you can offset a summer beach trip with free nights in a hotel, from hotel cards, the money you save there can be allocated to Disney or whatever you care to do.
I look at it as an overall budget and I take it from there. Sometimes I've done things like get discounted home depot gift cards on the Amex site with my Amex MR's and bought a $2k John Deere riding mower.
@SouthFayetteFan may or may not have done the same to buy a dishwasher (it may have been a different appliance!)
And, for Xmas my son had some tools on his
Amazon wish list. I bought them using home depot gift cards obtained from Amex using MR's. The cash I would have spent stayed in my account.
Okay, so this moves at your pace. It's a
job and I'm retired so I dabble in it a little bit. It pays to be organized. Some people keep spreadsheets. I keep lists but nowhere near as organized as some are. But than I don't have to be and I'm still happy to pick the easy fruit.
