The Boost Mobile 170GB $230 12-month SIM is on for $188 at ebay, which comes down to $173 with coupon HGTSAVE (expires 2-11-2023). If you're doing a multi-buy like me, it can come down to $167.36/card for 4 or more.
Couple this with the ebayplus deal (https://www.ozbargain.com.au/node/808968) for free signed shipping. I went with the TopCashBack option so I don't have to pfaff around with ebay gift cards. TopCashBack are offering 3% cashback on ebay purchases, but I don't know if this will track when linked with the HGTSAVE coupon.
There's probably some better deal coming up with Black Friday or something, but my families Woolworths Mobile plans expire 14 November, so it was time to jump for me!
This isn't terrible to be honest. You might look at this at first and think 17GB a month isn't much, but I've come to realise, with me working from home more, I'm not using as much data as I used to. this might be a better option for some than the 260GB/$240-$260 deals
