I will agree with mcs, that's all i will use is my debit card or savings that I have done specifically for cigars/ pipe tobacco.
I will do this on occasion is pay with a CC and then pay it off so I can get CC points and pay no interest.
Now, today, I am going to use the credit card over there at JR Cigar's wholesale nightmare they have going on. I scored 3 great boxes of smokes for way less than I would ever pay for them.
