i usually only use store cards for their interest free promos. 75% of the time i pay off the balance in time. i think i only need to make a purchase every 6 months or something. i guess ill call to find out. its the first card that has sent me such a letter. ive had other store cards with 0 balance open for years. maybe their just bluffing. the credit limit it on it is much higher than i remember so maybe theyre just trying to get me in on a big purchase. ill probably buy some toilet paper and call it a day lol
