free1
Free fries with any burger, just present this coupon at the counter. The coupon comes from signing up to newsletter but is not unique. The coupon says it expires on the 25th of april but if you change the date in the domain the expiry changes similar to the free birthday burger.
If you do want to sign up for the newsletter although it is not required for the free fries you can do so here(burgerwisconsin.co.nz)
If you want to use a different voucher to receive free fries you can use this one(burgerwisconsin.co.nz)
When ordering online use the code free1 to get free fries and dip.(burgerwisconsin.co.nz)
Great deal! With the direct link, you don't even have to sign up to the newsletter and anytime you want free fries, just change the date in the URL to the day's date and generate a voucher. You could use this multiple times.
