A nice deal spotted at the local Woolworths store in West Gippsland [VIC]:
Buy 1 x bag for $24, save $5.49 (18%)
2 x bags for $42, save $16.98 (28%)
3 x bags for $57, save $31.47 (35%)
This is fairly cheap as an 8kg bag normally retails around $24-26 mark (at my local store anyway)
They had 3X 8KG for $39 a few months ago
