If you are a new Audible member, I believe you also qualify for a free month (1 free credit to use for any audiobook), plus the benefit of paying only $4.95 a month for three months.
PLUS a big bonus for CashRewards members: get $10.40 cash back! See https://www.cashrewards.com.au/coupons/free-trial-then-4-95-…
How does CashRewards work??
