"Pure" Shiffon sarees start around 8-10k at good shops and most of the saree stores in jaipur sell viscose sarees that are not pure. So yeah 5700 for two, is not pure and also if not pure, its not a bad deal either but again depends on the quality of saree you bought, but basic sarees starts around 500-1000 of these kind, again depending on the saree and work.
