The Prime Surprise Sweets Dash Button is completely FREE when you use promocode SWEET50OFF at checkout. Yes, your total will litteraly be $0.00. This deal is only available for Prime members. The first time you use the button to order Prime Surprise Sweets you’ll automatically receive $4.99 off of the $18.00 purchase. This is likely a price mistake where two promotions are overlapping and it will not last long.
There are also several Dash Buttons on sale for $2.49. The above promocode only works on the Surprise Sweets button, but all $2.49 Dash Buttons will still receive $4.99 credit the first time they’re used, making them essentially free with a $2.50 profit.
