Official Black Friday deal from Boost Website. They also have the 100GB for $170, which isn't a deal compared to what's already put up. This one looks to have a 20GB bonus already built in because the recharge is 240GB. I bought it because I've always for no luck with Officeworks price matching and for the other deals, it was too much trouble putting the codes in, adding delivery just to save a couple more dollars.
No nonsense checkout from Boost + $6 Cashback from Cash rewards. Deal.
Note: I bought this on the 23/11 when the deal first came out (because I was desperate) but you can consider waiting for any flash cashback deals between now and 29/11 as well.
