My first charge account was in 1974, Lazaras Department store in Columbus with a $300 limit on smalls and $800 on major things like furniture and large appliances. Right out of H.S. I applied for a Sohio gas card (now BP). Those two could be had by anyone with a pulse! Since I paid off (usually) and on time, by the time a year rolled around They were up limited to $1000/3000 and $500. (Years later I found out good jewelry was in the major appliance category, and my limit was $11,000, Over the years I bought my wife probably $100K at list price by with stacked on discounts that were cardholder only, always got 50 to 70% off and paid off in 2 or 3 months!!)
The other day I applied for a B.J.'s MC to get the extra 15 cents a gallon off of gas (10 to 20 cheaper than Costo and 45 to 60 cheaper than retail), and I noticed a huge limit! So, I looked up my FICO score and it was a huge as it has ever been! No first mortgage, a way under drawn PCL and 1 other credit card with zero balance. Utilities paid on time. Anybody with a pulse can get a credit card. The big profit is in late fees and High Risk interest rates for slackers.
I still have a Kohl's Card but you don't have to carry it to use it, so that's one thing less in my wallet! Only use it with cardholder discounts around Christmas. My brother does the same except; after checking out he goes to the service desk and pays it off before he (or his wife) leaves the store! (yes, you can pay before they even send a bill!)
