First time post, sorry for any mistakes.
Found a $100 Xbox live gift card (Only valid in Australia) for only $56.89. ~ 40% off
I would also suggest you purchase the G2A shield as it acts as insurance in case the code doesn't validate.
(For people that don't understand how gift cards work)
So pretty much you spend $56.89 (or $58.39 with the G2A Shield) and get $100 dollars to spend on the Xbox live store which includes Games, DLC, Movies, ETC

Worked like a charm!!! Many thanks OP, 40ish % discount is not something you get all days.
