Spotted this new basket deal on iHerb. If you buy Madre Labs Madre-C and Eureka! Berries together, you get both for just US$20. Postage is still only US$4.00. The iHerb calculator comes to AUD$23.82 delivered.
This is a considerable saving on their normal pricing for these products which are normally US$37.07 and US$26.57 respectively. Might be worth a try at this price with the winter cold and flu season approaching.
And this deal can even be cheaper - if it is your first order feel free to use my affiliate code OKE962 for $10 off an order of $40 or more, or $5 off any order under $40. I tested it and using my affiliate code the order will come to AUD$13.90 delivered (their system considers the order is over $40 for some reason or another, I guess the heavy discounting at checkout)
super berries = waste of money
