Just found this deal but it expires today. Eco Store has 20% off all products, great deal if you normally purchase their products. Shipping is $12 but they have the bulk packs which are good value compared to normal retail packs. I always use their dishwashing powder - normally pay $8.99 for 1kg at woolworths (cheapest I've found and rarely on sale). Yes I know this is not a bargain compared to other cheap/ bulk stuff but it's the best I've found for more eco friendly and great cleaning. The liquid dish detergent for handwashing also great. Today the 5kg dishwasher powder is $31.99 plus $12 shipping - very worthwhile if buying more than 1 bulk item.
