Because the benefits overlap and youll be paying an extra annual fee for no reason.Why not? Minimum would be 15k between both.
I just need like 3k to use to purchase my products and it would raise my credit limit/lower my utilization.
CSP IS 2x on food and travel, 1x on everything else
CSR is 3x on food and travel, 1x on everything else
