Should I switch from the HSBC Premier World Mastercard to the Amazon Visa? If not, which credit card will let me save the most money rather than be rewarded for spending more?
I have the HSBC Premier World Mastercard
with a $30K credit line and I meet the requirements to not have any sort of fees and I watch my books vigilantly. I make maybe 90% of all purchases on the card and pay off the full balance every month, and have been doing so for the last ten years. On average I'm burning through about $1250 a month. The rewards the card provides are almost completely useless to me: I don't do a lot of travelling, and I haven't left the country in years. I'd rather have benefits with immediate relevance than free airplane tickets after five years of spending. The security of the credit line is nice, but I don't think I've ever had a balance over $5000. If, God forbid, I need to borrow a large amount, I'll find a cheaper way to do it than a consumer credit card. I have no car-related expenses and very, very few home-related expenses (in the "repair" sense, I live in a co-op apartment.)
I'm wondering if the Amazon Visa is right for me. They are the only retailer at which I regularly spend large amounts of money (I buy all house supplies in bulk on Amazon) so the triple-points toward other Amazon purchases makes sense. Again, the rate doesn't matter because I plan to pay off the balance every month as I have been doing. Stories of a low credit line worry me a litte: does anyone know how a credit line is determined in this case? My credit score is in ~780-790 and I'm reading a lot of conflicting things with not enough context to figure out what is going on. My Mastercard was opened under some pretty unique and unrepeatable circumstances so I'm not expecting $30K, but I think I'd need at least $10K to feel comfortable opening the card.
So, should I go with the Amazon Visa? Are there other options I am not seeing? I've looked at those "figure out the best card for me" websites and haven't seen anything to make me switch cards.
If I do open the card, is it better to keep the Mastercard open? Is that going to affect my credit somehow?
