// THE NUMBERS

The average Aussie household overpays by $50 a week.

Not because deals don't exist — but because comparing prices across four chains every week is a full-time job. Grossa does it for you, every single week, in seconds.

LEARNS AS YOU SHOP
Gets smarter every week

Woolworths, Coles, ALDI and IGA — monitored simultaneously. Grossa finds the best price for each item across all stores and routes your order accordingly.
AUTO-ORDER
One tap. Done.
Review your optimised basket and approve with a single tap. Grossa handles the checkout across each store's delivery service. No app-switching. No repetition.
SPECIALS RADAR
Half-price alerts that matter
Only get notified about specials on things you actually buy. No noise. Just a weekly summary of the deals worth acting on, tailored to your household.
