I found out about the BrickLink website from a very nice and helpful LEGO representative whom I had contacted to ask whether or not a certain DUPLO set had been discontinued.
The night that I decided to buy some used bulk bricks, the BrickLink site was down. Since I don't find myself with too many free nights where I can internet shop, I decided to give eBay a try and found a lot of used bulk sets. The sellers on eBay do a pretty good job of photographing and describing what their bulk sets contain. I wanted a set that just contained the standard rectangular and square faced bricks and some of the eye bricks. I was able to find a set with about 200 pieces for less than $40.
I guess instead of building an octopus, we should have been making a hurricane warning flag since Hurricane Isaac has just entered the Gulf. Hang on everybody down there and stay safe!!
