The town was set to lose all of its cash points in April when Lloyds, which will be the last bank left in the town, closes its doors.
But Cardtronics has now installed two ATMs in the High Street, both hosted by Co-op.
Neil Smith, store manager of Radstock Co-operative Society's Glastonbury store, said: "We are delighted that Cardtronics UK have agreed to the installation of the ATM machines following our approach to them shortly after we heard the news about the bank closures.
"With the new service, we are able to offer our customers the vital convenience of shopping where they can also access their money easily.
"We are sure this won't just be an added plus for our own business, but it will strengthen footfall and spend for the entire high street of Glastonbury."
One of the cash points will be inside the store and the second ATM will face the street through the shop front. Both will be free.
Tim Halford, commercial director of Cardtronics UK, said: "Glastonbury is the latest example of local communities and businesses joining forces to preserve people's access to cash by installing cash machines within local shops after the last bank in town has shut its doors.
"However, even these sites are at risk in many locations because of the hefty business rates bills that retailers have to pay for their ATMs while banks don't."
"As such, it is now more important than ever that we rally to support local communities to keep their high streets and town centres alive and thriving."
