Pretty decent price for these, as they're listed for $20, plus you get an extra 10% off as they're part of the EOFY sale (discount applies in cart)
Price doesn't include delivery - free if you spend $50+ & are a Club Catch member
Prices elsewhere
iHerb @$33.47
bodybuilding.com @$33.70
Sidenote - seems COTD are now known as Catch.com.au
Overall they are cheaper here than other sites

So mix and make 50$ for catch members :)
