I've been there one time! The first day my friends and I went, we didn't spend a dime! We were awestruck! However, we made the "mistake" of going back the next day...well, it was a good thing we were in a van!
One word of advice, if you see something you like, buy as much as you can. I got home and decided I'd like a few more yards of a batik and they had already sold it all!
I am so envious! Hope you have a safe and blessed trip.
