Went in store yesterday and was told the offer for the Z flip 3 for $599 upfront (or $699 for the 256gb) on a 12 month $69 plan with unlimited calls / texts and 80gb data was back on until the 10th October. A deal exists for the Fold 3 also, but I'm unsure of those details.
If you missed out last time it may be worth going to your local store!
I signed up today. Ample stock available at many stores in WA.
Thanks op.
People like me in VIC and NSW will forever miss this deal. It is unreachable to us.
