Say there is a waitlist for SSR June UY. And person 1 wants 50 points, person 2 wants 150 points and person 3 wants 30 points. And they buy back a 175 point contract. They go to person 1 and sell them their 50 and then they have to skip person 2 since they only have 125 left and they sell the 30 to person 3. it is best to put a frame of points you want ie: 60-100 (so in my ie above person 2 should have asked for 100-150 and then they'd get a call with the 125 and could decide yes or no). And when they call with points you can always take less than you were on list for but most of the time you can't take more as there is another person on the list behind you. Though if there isn't another person, you can ask for more if they have them. I have bought 4 small direct contracts. One time I called up and they happened to have points for me, no wait. Two times I was on a waitlist, one came through in 2 weeks and the other was a month. Last add was CCV so no wait there either. Good luck.
Oh, and they don't hard sale you. It is easy peasy to call a guide and tell them what you want, like ordering a pizza. Also, I have a great guide I love. Wish I could post her name.
