So I've been reading about manufactured spending for a while. I've got a Sapphire Preferred I've been wanting to knock out the sign-up bonus on soon as I'd like to take advantage of those points for a flight coming up. From my understanding, there are a few banks you can use the CSP to load an account with (without it getting marked as a cash advance). Would I be able to open one with about $1500, and just pay the card with that bank I used it on at the billing due date?
