0 stars if I could. This shop is listed on Vikings certified list of rug shops but don't let that…read morefool you. Our guide talked this place up and claimed the Turkish government was investing in the dying art of rug weaving which allowed these merchants to offer free international shipping and the best prices around so buying and this "collective/co-op" would really be helping support the craftspeople in the area.
When you walk in the show begins. They have you file into a room where you get to see the silk being spun off cocoons. They explain they'll show you the process from start to finish and walk you to their show room where they have an artisan set up in the middle of weaving.
At this point they just emphasize they're happy you stopped by and are happy to treat you hospitably as they show you their products.
They show you different materials and have you feel the rugs. Then they roll out carpets on carpets and start sizing you up. At the end of their presentation they have sales people walk up to you and they refuse to negotiate. They instead stick to their first price and continue to drone on about quality and labor.
Imho if your tour guide/excursion takes you here, try to go off on your own at that point. Go enjoy the beach or just explore the city on your own.
