Do Category Bonuses Matter at This Level of Spend?

Do you need to focus on the right cards for what you spend money on, or should you just be focusing on welcome bonuses? Yes. To the extent that you're signing up for new cards regularly, the bonus is going to far a outweigh a category bonus. Even if half of that is at the grocery store, it won't make enough of a difference to justify not getting new welcome bonuses. Most welcome bonuses are between 50 and a hundred thousand points, i'd say, for three to six thousand dollars spent.
