I am new to this forum and quite amazed at how many posts there are in this thread. Would expect to see this kind of interest on Fat Wallet.
I agree with the above poster - I have really only used the buying coins idea to reach minimum spends on credit cards.
But after reading a few of the pages here (certainly not all 151 pages - gosh) seems many folks here doing this at $5000 a time. I can only assume that is some heavy box you get with 5000 coins !!
I might have to consider this with the SPG Amex - do it 4 times for 20K miles, then get 5K bonus when transfer to an airline.
Or is there a better card to use???
