Whoa. Can some please tell me if I have a reading comprehension problem here.
Admittedly, Marathon Man's posts, are, well, marathon in length and I may have missed something.
What I think he is saying is:
1) If the stores policy if to give back cash for small items, or partial items, returned bu purchased on credit.
2) -and- you participate in this transaction as part of your day-to-day activities. i.e. the transaction wasn't entered into only to earn miles.
then there is no problem. ???
