Credit Card Round Robin Scheme - SCHEME - not a scam
get 13 credit cards
1 card is your base card the other 12 are for the Round Robin
fill the base card with your merchandise purchases. when the bill is due do a BALANCE TRANSFER to card #2
unless things have changed credit card companies are happy to do a free balance transfer and depending where you hit the cycle you should get at least another 30 days before interest begins to apply
for the next month fill up your base card with your normal merchandise purchases.
transfer the balance on the base card when due to card #3
when the bill is due on card #2 transfer the balance to card #4
keep transferring the balance due to different cards going round and round
Pay down the principle when you want to and it is convenient for you, not when they demand it or start charging you interest
Eventually some of the cards may say no more balance tranfers
But by then you should have been able to get at least one year free of interest
Nothing illegal or unethical about it.
Must have been a while since you have done this because cards charge 3-5% for a balance transfer now. Sometimes you can get a promo with free tranfers but that is limited.
