Looks to be a 'Black Friday' repeat of the recent 90 day 32gb/month deal. Offer ends 11:59pm NZDT 02/12/2020 unless sold out prior.
Voucher itself expires at 11:59pm NZDT on 15/01/2021. Make sure to turn off autorenew if you already have a Kogan Mobile plan going so that your existing plan does not autorenew - then you can use the voucher code to renew.
Just over 1c per day. This one isn't just a new customer offer either - existing customers can get this.
Absolutely fizzing; after I finish this deal, I'll have had six months of mobile for $2.
Plus if you have a 5G phone compatible with the Vodafone network you will likely get 5G access, although it is not advertised and might disappear at any time.
