Amazon introduces $9.99 unlimited grocery delivery subscription with Prime

U.S. Amazon Prime members can now order as many grocery deliveries as they’d like each month if they pay an extra fee and meet a certain dollar amount.

The additional monthly fee of $9.99 gives Prime members living in one of 3,500-plus areas access to Amazon’s new grocery delivery subscription, according to the company.

The unlimited deliveries offered through the subscription, which was introduced Tuesday, apply to orders that cost at least $35.
