I am in the same spot you guys are. My GPAs were calculated almost 3 weeks ago, and in the email it said my apps would be mailed the "next mailing date." Since it seemed that at least a couple mailing dates should have gone by, I emailed them and this is the response I got:
PharmCAS does, on average, one weekly mailing per mailing cycle. It should be said that PharmCAS could produce more than one mailing per week, but there is no way for Applicant Support Representatives to know if that is the case (the same can be said for WHEN they mail the applications out also).
Regardless, your Pharmacy designations have access to your application status online. And again, once the hard copy is mailed, the schools will have immediate access to an electronic backup file of your application that we send them directly.
So, no real answer as to WHY it is taking them so long to mail them out...
