Alright so I was on newegg today looking for some extra case fans, so I decided on ordering a few of these but if you look at the "Quantity Pricing" chart on the left side of the page it shows that if you order more the shipping and fan price will go down. So originally I was going to order 4 which would be $6.36 + $17.18 shipping but I saw that if I ordered 1 more to make it 5 the price would drop to about $15 instead of getting 4 at $23. But then I noticed on the little quantity price chart that if I was to get 15 fans the price would only be $1 a fan and free shipping making it $15 for 15 fans instead of the original $23 for 4 fans, how could this be? Is it some error?
