Amazon was charging users of Amazon Fresh $14.99 a month, but now the company is dropping the free for Amazon Prime members in the US.
If you are a Prime member in the US who pays the $119 a year or $12.99 a month fee then you will now get Amazon Fresh and Whole Foods Market deliveries for free.
There is a minimum order for each order of $35 in the US or $50 in New York to qualify for the free delivery.
Amazon is trying to compete with other companies who offer free delivery on groceries when you spend a certain amount. This new offer is only available to existing Fresh subscribers, you can request an invite to Amazon Fresh if you are a Prime subscriber.
