Voucher must be purchased by 30/11/21 in order to get the 50% off pricing.
Once purchased the vouchers need to be 'activated' by the 31/12/21 for the Small and Medium Plans and 28/2/22 for the Large Plan.
EDIT: Kogan originally stated the Large voucher needed to be activated by the 28/2/22. This has now been changed to fall in line with the other vouchers and all need to be activated by 31/12/21.

What's the coverage like with Kogan? Would consider switching from the $16 a month skinnt plan I'm currently on if I'm likely to get decent service coverage.
