Not sure if mods allow this kind of deal, but thought to post it for visibility. Essentially a profit SIM for the $35 Boost SIM (now discounted to $12, with $11.88 cashback + random top ups ($0.15 to $0.25)).
TA has mentioned in the comment of the original deal:
Anyone that buys a SIM from this deal up to 10:30am AEST tomorrow (Sunday) will have their cashback randomly topped up by $0.15, $0.20, or $0.25. Accounts will be updated by noon Sunday. This is funded by TCB (not Boost). It’s not much, but just a small token of our appreciation for your support.
It's very visible now 😀
