I have heard that there is a rolling limit on purchasing items with LPs. I have also heard that if you buy any amount of coins that will increase your permited purchases. I plan to go to Vegas the last week of June and would like to get 4 "O" tickets. I almost have enough LPs to do it now but will surely have enough soon. Since the "O" tickets are sold individually will I be able to get 4 at one time or even 2 now and 2 more in 30 days?
