These are my new favourite bars, and the Peanut Nutter is the best tasting imo (although it's not very "peanutty" if you know what I mean).
Normally when protein bars are so discounted at Catch they are short-dated but I can't see these are, there's no mention of expiry. Caramel Chaos also available for $16.95 for a box of 12 (link below)
Also seems to be 3% back at Shopback but I rushed my order before I realised that.
Word of warning, a couple of the biscuit flavours are heavily discounted too, but I have had these in the past and they taste awful… really horrible mouth-feel, I don't know what it is. Buy them at your peril.
Shipping shows as $11.95 for me for one box, but free for Club Catch members (can get a free month trial, after which monthly subscription is only $6.50)
