I've noticed that pricegrabber sometimes only puts up search results from merchants that specifically pay them to list them on their site. One item, sold by a major online retailer, was listed at $27. Pricegrabber search results returned merchants that had prices that went from $37 and up. Almost all the merchants on that search results page were relatively unknown obscure online merchants that I have never heard of. While that major online retailer is a popular site frequented by many people. That was really strange.
