All of the places I have bought from were named here, except
Orthodox Monastery Icons, whose name, sadly, is very much like the fake Hindu site, except this is a legitimate Orthodox monastery,
Paracletos Greek Orthodox Monastery, in South Carolina.
I have
this lovely icon of St. Dymphna on my wall, from them, and was happy with the quality.
Several of my icons I got from my cathedral bookstore, who purchased them from St. Isaac Skete (skete.com)...but see above for their status, so I don't know.
I 'rescued' an icon of St. John the Forerunner from a secondhand shop off Mercari, which was also from St. Isaac Skete, and was apparently blessed by a priest at some point.
Speaking of Mercari, I keep a search running for 'orthodox' and 'orthodox icon', and sometimes find some nice icons and books on there.
Here is a shop I found that seems to have some nice ones:
holyseed - and they are also on
etsy. They appear to be handmade by monks or nuns, but I don't have any information on which monastery they come from.
I bought
this small Anastasis icon off Amazon, and they have a number of other styles. It's tiny (roughly 3 in x 4 in), but I was happy with the price and quality. Having said that, the company,
Logos Trading Post, is not specifically Orthodox, sort of a clearinghouse of 'all things Christian'.
And of course, there's always eBay, but you have to avoid Monastery Icons there, too.
