WATCH YOUR EMAIL for this and other offers - if targetted, you need to activate. Last quarter it was 10% back on all "online purchases" - minimum $300 spend, maximum reward $100 ... this quarter it's the same $300 min spend/$1000 max spend ($100 max reward per month) across all three categories. Clearly Citi is trying to get me to use this dormant card! Considering the outrageous APR, absolutely a PIF but for $100 a month, definitely worthwhile!
I received that email too, and if I wasn't currently overseas......I also got one when I was home during the holidays, for a $25 statement credit after spending $50 outside of Sears/kmart. Citi has been throwing these at me lately too!
