zZounds.com has an entire section devoted to microphones.  Their selection is extensive and impressive.  They sell microphones from as low as $9.99 to upwards in the thousands.  Their brands include OnStage, Shure, Marshall Electronics, Rode, Peavey, Sennheiser, K&M, Nady, Samson, Audio-Technica, Neumann, Earthworks, and much more.  Many of their products feature a giant “Free Shipping” arrow, so you can avoid ridiculous shipping fees  when you shop at zZounds.com.  All microphone products on this site also feature ratings from visitors, on a scale of 1-10.  Product information is extremely informative and products are easily located (we found the Neumann U87 and M-Audio Solaris with just one click).  Also, products are almost always cheaper than the suggested retail price.  Our visit to zZounds.com proved to be more than satisfactory.  We were able to locate just what we were looking for: prices are decent, the product range is extensive and product-related info was very helpful.  In addition, zZounds.com supplies a Blowouts section, which features dozens of products with very low prices.  Some product prices are even "too low to show.”  For these products, visitors must call in to get the price of the product – obviously more of a selling technique rather than a way to offer low prices.  A downside worth noting here is that microphones aren’t returnable at zZounds.com due to “health laws,” so make sure you definitely want what you’re purchasing from here.
