If they don't send it, you could resubmit your info, put your school name under employer and your occupation as student. That is generally good enough for these sort of subscriptions.
It says on the site that if your info doesn't satisfy them they send you an invoice with the first issue. So, they don't ask anyone for their credit card number at the time that the application is filled out. My guess is that you could send them something identifying yourself as a student back with any invoice they send and they would make your subscription free.
You can always view the Pharmacy Times
articles online if you are pre-pharm. Based on the statement on their website, I do not believe pre-pharms would be eligible for a subscription unless they currently held a job as a technician, etc. in a pharmacy setting. In the FAQ/Links thread
that is under construction, there are already links to websites for many other pharmacy magazines
