I've had good luck in the past with finding coupes in Etsy's Vintage section. They aren't typically sold in large quantities, but the variety is decent and the prices are (generally) reasonable. Here are a couple of searches that turn up relevant stuff for me (though there's a lot of overlap): http://www.etsy.com/search/vintage?q=champagne+saucer http://www.etsy.com/search/vintage?q=cocktail+coupe http://www.etsy.com/search/vintage?q=coupe+glass
