When I bought my PowerMac, I opened an Apple Credit account, operated by Juniper Bank (Barclays PLC). They offered a 6-month interest-free period, and at the time I convinced myself that I’d pay it off before paying their outrageous interest rate. Fast forward three years, while reconciling some accounts and cleaning up Quicken. During the life of that loan, I paid a silly amount of interest and made many late payments by neglecting to create reminders. The cost to finance a $4500 purchase was nearly $2000. Stupid. Of course, I was the dream customer for credit card companies. I now use an electronic bill pay service, and prevent these financial mistakes. It gives me enormous satisfaction to cancel that account.
