NEW YORK (AP) Amazon's futuristic "Dash" buttons appear here to stay.

The e-commerce powerhouse is expanding the number of available buttons, which reorder products at one touch. It's also making them virtually free.

Last month Amazon launched the "Dash" buttons adhesive buttons designed to stick on any household surface near where you may need to reorder products for about 18 brands, ranging from Bounty paper towels to Tide detergent.

Now they're adding 11 branded buttons to the program, including ones for Ice Breakers Mints and Hefty trash bags. And for every $4.99 button customers buy, they'll get a $4.99 credit back into their account.

The buttons are available to members of Amazon's $99 annual Prime membership program.
