The Amazon Echo has just gone on sale for $84.99, which is $15 off the regular price. The Echo Dot is also on sale at $39.99, which is $10 less than you’d normally pay. Both of these sale prices are fairly mediocre and come around about every other month. That said, it’s certainly better than paying full price. This sale is expected to last through the end of the month and end on May 31st.
