For Prime members only, Amazon cuts a range of its Amazon Dash buttons to 99 cents via coupon code "DASHBDAY". Even better, you'll bag a $4.99 Amazon credit after your first press. Plus, all orders receive free shipping. Assuming you'll use the credit, that's a buck under our mention from a month ago, a $9 savings, and tied with our Cyber Monday mention as the best deal we've seen on Dash buttons. A limit of three per customer applies. Deal ends April 7.
