While learning MS techniques I seem to make as many mistakes as possible.
Today I was in an OSS that had coveted GCs.
$200 Visa GCs that I've never actually seen on the rack in an OSS.
I went wild (for me) and bought two and some Petco and Groupon GCs for good measure.
I thought to myself, prematurely, Wow, that'll be like 2500 FF miles!
Visions of the Bahamas occupied me at the cash register.
A few hours later I realized I had used the wrong CC because it was the same color (blue) as the right CC.
Oops!
FF miles earned will be 1x spend instead of 5x spend
What mistakes did you make as a noob MSer?
Want to know so I can laugh and avoid them.
