[VIC] $15 + $6.05 Fee GA Tickets to BBL Melbourne Stars Remaining Matches@ Ticketek

I received an email from MCG that said to use code STARS20 for discounted GA tickets for remaining matches. This code makes tickets $20 + fee (maybe other ticket teirs are discounted with this code too?) but I also guessed a code last week using STARS15 which gives you $15 per ticket + fee and seems to be working for all remaining matches.
