I'm buying an off-campus meal plan for this fall. I found the form on the hospitality website and filled it out...now what? Do I mail it to the address on the form? And are they accepting them this early or should I wait a bit?

I'm pretty sure you have to go in person and drop it off, as they need your Student Card.

You could email them though

[email protected]

or 905-525-9140 extension 27448

and their mailing address is:

Mac Express Centre,
McMaster University
1280 Main Street West, Commons 128
Hamilton, Ontario, Canada L8S 4K1

Edit:
It depends on what plan your are getting, if you get the Freedom plan, the money stays with your forever, but the term plan expires after your selected "term"

For anyone reading this who was wondering the same thing: I emailed Mac Express and there is no deadline to send it in, you can mail the form to the address above, and they do not need your student card.

Go to Commons. She will be asking for your student card and your form.

I applied in early March (after discovering the Freedom plan). You get discounts for using it!
