With Shopback/Cashrewards etc not offering much in the way of cashback for alcohol these days, it is worth mentioning that if you have your birthday 'defined' in this Christmas block (20-24 DEC), you will often receive 10% coupons from the likes of First Choice, Liquorland, Vintage Cellars and so forth a few days prior to your birthday.
Vintage Cellars for example sent a $10 off 100 coupon - combined with the $50 Roku Gin for today, results in purchase of two bottles for $90.
It may be too late for this year (or maybe not?) - but definitely worthwhile trying out.
I have not received any alcohol vouchers. Where does one sign up for these?
