For myself it is
1) Use: Is this something that I might use either directly in my game or simply as a source of information (or inspiration)? An example of the former would be GR Psychic's Handbook while the latter would be GURPs historical books.
2) Author and Publisher: I don't buy products blindly from any company, but I generally keep watch for products by authors and publishers whose products that I have enjoyed in the past.
3) Reviews and threads: Generally, reviews and threads alert me to products from companies with which I am not familiar. If a product sounds interesting, I will check it out in a store-- for example, ENWorld was how I learned of RPGObjects' Blood and Fist.
Regardless of the above, I never buy
1) shrink wrapped or pdf products unless I have already read through the product. Too many shrink wrapped products in the past have turned me off from buying products unseen.
2) published adventures: I already have several classic modules for reference (e.g., Keep on the Borderlands and Ravenloft). Primarily, I prefer to design my own adventures.
3) new settings unless the setting is one that I want to actually run as a campaign. As a general rule, I prefer creating my own campaign settings.
