Hi mcdmilatos ?
Don’t know of any in right in your area but several of the garden centres around Hersonissos do sell it and would deliver over to you.
Post here or e-mail me through my site [www button below] if you need directions
Right weather for it now anyway
Not sure about your immediate area but you could try these people at Malades, south of Heraklion. They seen to travel everywhere and have just done the whole stretch along the front at Rethymnon. All they do is turf so should be more reasonable as no middle man!! http://www.fastgrass.gr/lang1/index.html
