I did a 2 month "don't buy from Amazon" which forced me to look around a bit, but there are lots of alternatives. Amazon is amazingly convenient, but it's coming at a price which is higher prices and 1 vendor issues. You can't really say it's a marketplace with all the SEO and buying positions going on either. I still get stuff from Amazon occasionally, but I found there are plenty of alternatives out there if you can wait an extra day or two.
