In recent weeks, Theodoros Mavridis has bought fresh eggs, tsipourou (the local brandy: beware), fruit, olives, olive oil, jam, and soap. He has also had some legal advice, and enjoyed the services of an accountant to help fill in his tax return.
None of it has cost him a euro, because he had previously done a spot of electrical work – repairing a TV, sorting out a dodgy light – for some of the 800-odd members of a fast-growing exchange network in the port town of Volos, midway between Athens and Thessaloniki.
In return for his expert labour, Mavridis received a number of Local Alternative Units (known as tems in Greek) in his online network account. In return for the eggs, olive oil, tax advice and the rest, he transferred tems into other people's accounts.
"It's an easier, more direct way of exchanging goods and services," said Bernhardt Koppold, a German-born homeopathist and acupuncturist in Volos who is an active member of the network. "It's also a way of showing practical solidarity – of building relationships."
