Um, lets see: 50,000 tickets. If it took 1 person 50 seconds to place each ticket into an envelope and label that envelope that would be about 2500000 seconds or about 695 hours. So, if there were 10 staff members that would take about 11 - 8 hour days to pack all the envelopes. I am probably guessing too low on the actual packing time, since USPS tracking envelopes would require more effort to pack.
That is assuming all the tickets are available and that all of the shipping labels were pre-printed.
There is no reason to expect to receive your ticket for at least a week. Remember that there are holidays coming up as well.
