Trying to boost my credit score a little more by making small monthly purchases on a CC and pay off at the end of the month. Looking for a card with 0% annual fees and 0% APR (for a year or longer). What would you recommend and why? (Before anyone rants about why CC's are bad. I have had several store CC's and never went into collections or made late payments. This is only to increase my credit score to the 800's (right now i'm at a 780, and getting to 800 is a personal goal of mine).
