Problem is they must pay it back that way ( except 5D). I did one with Oly, have to waste free wd on the e-check before getting rest NT, and paying for it.
Here's a nice way to do it. Deposit to Mansion NT instant, roll it once, and withdraw next day. No fees and it's real NT money, no 8.9 %, no week wait, no must be paid back to e-check, just bet whatever you were going to bet anyhow. Only problem is limits.
