Where to buy Greek Key link necklace?

Hello,

I’m in Canada and I came across a Greek woman who was wearing a necklace like this one:

She bought it in Greece. I’m fascinated by this design/ necklace and I’m interested in buying one. I may be able to travel to Greece next year so I might buy it there but I might also order it online. Do you have recommendations for online jewelry shops or places I could shop at in Greece?
Does the price on the link posted sounds fair and do you know if this retailer has a good reputation?

Thanks a lot!
