This Subway Canada Customer Appreciation Day is valid mainly at Southwestern all Ontario Subways. On March 3rd, 2009 from 11am till 7pm buy a footlong Sub and a 21 oz fountain drink and get a second footlong Sub for free! No coupon necessary.
I’ve found that in general the owners of each Subway store get to choose which promos to participate in so don’t expect this at every Subway location.
Update: Looks like this Subway Canada customer appreciation day is at all Ontario Subways and not just Southwestern Ontario 😀
Call your local Subway to double check!
