Amazon's Dash buttons are making shopping lists a thing of the past. You're a Prime member, after all, and shouldn't have to trouble yourself with such things. Since the little connected buttons became available, nigh on 30 brands have made ordering mac and cheese, diapers and washing powder that bit more convenient. And to celebrate Dash's first birthday, Amazon today announced a significant expansion, with a total of over 100 different buttons now on hand to take your orders for thousands of individual products.
