The Anjuna flea market is worth a visit and you'll find most things there, however, it gets extremely crowded and is massively touristy. You need to haggle extremely hard as the prices are ridiculously over-inflated. You can reach the market by boat from other towns along the coast and it's a pleasant way to get there. I personally prefer more local-style shopping, but for a one-stop shop this is a pretty safe bet. That said, I'd recommend Mackie's night market over the Anjuna one simply because the evening temperatures make for less frayed tempers and a much more chilled atmosphere. There is also some great food and music at Mackie's.

You can get some great bargains and local food here but you must go early. Get there as soon as it starts to open. Get a driver to take you and ask him to wait, doesn't cost a lot either.

You can meet people from everywhere, even some that you know from your country. They are different special items you can buy, in a very special ambient.

A good place to pick up souvenirs when you are actually sober.

If you can't find it here ... it aint worth buying!
