@Jonavin@will13am can you imagine pouring gravy over cheese curds and fries and then having it sit at least 24 hours? That's a envelope no one wants in their mailbox. Sorry, have to mark this one as 'Not for us'.
Need to think freely. Coupon will never spoil (or only on a date you want it to). You should hav ethat as a question for the new Product Manager you're hiring. Hire the person with the best idea about how you can include fries (or poutine) with their SIM card order.
