Just dropped from $31.99. Repeat of the June deal. At $26.99 with subscribe & save discount it's as cheap as it gets on Amazon for the individually wrapped bulk pack. 300 Biscuits at $26.99 = $0.09/Biscuit.
Likely matching Catch $29.99 + Delivery (free with catch). Alternatively it's available from Woolworths for $1.40 8pk (8x2p), if you wanted a smaller pack. Edit: Woolworths actually seems to work out cheaper if you buy in these 2 packs instead of individually packs as per discussion here.
Free delivery with Prime, $39 spend or subscribe & save if you already have an active subscription. You can change your Subscribe & Save date here. You can cancel your subscription here. The price is NOT locked in.
