Ideally you would make these plays quickly to have an opportunity to get them back by June when these players will most likely be in their Championship games and the demand for these cards will be at the highest of the year potentially increasing the profit margins! Right now PSA bulk orders are taking on average about 4-6 weeks from the time you mail them out to the time you get them back. Even if you miss out on the peak of these players if any of them cross over to a PSA 10 you will make money!
