After 50 years of smoking, I quit over 5 years ago.
I live in central Illinois, My mother,whom I visit as often as I can, lives in southern Missouri. Every time I visited her, I stoced up on lower tax Missouri cigarettes, saving about $20 per carton. The money I saved more than paid my expenses for the 650 mile round trip.
On an early occasion of doing this, I had a clerk warn me about paying with a Visa debit card. He told me that Visa and other major cards were reporting such purchases to other state's government. From then on I paid in cash.
