yes. with great success. my friend got par 20s and mr16s for under 3$ ea with great quality a few years ago. you have to order bigger quantities, though. they will even make led to your spec - beam spread, color, base. i suggest buying samples from them first though.
here are some manufacturers you can contact. they have live chat thru Skype typing in funny english

You need to be more careful, while ordering anything from China as there are chances of you getting victimized with low quality products and this is applicable for all products not only LEDs.
