First Choice seems to be rebranding to "Liquorland Warehouse".
Go to the store locator on the First Choice website and you'll see an offer for $10 off $30 online spend.
You have to select a store that has been converted to a Liquorland Warehouse - a link will take you to the Liquorland website.
The $10 discount is automatically applied when you add $30+ more to your cart. It can be used up to five times apparently.
It claims to apply the code TAKE10, but when you try to add that code without following the above steps it doesn't work. Doesn't stack with the sitewide 10% off deal ( https://www.ozbargain.com.au/node/922524) but will generally work out as better value for any purchase under $100. Conditions here:
Get $10 off when you spend $30 + in one online transaction. Offer ends 28/02/2026. Auto applied at checkout after savings and discounts. Limit of 5 redemptions applies per customer over promotional period. Standard retail limits and a minimum order of $30 applies. Excludes Uber Eats, DoorDash and Menulog. 18+ only, ID must be required.
if you initially select a old 1stC, then change to a LL it seems to work.
