Why the huge variance in prices on Cisco hardware and service agreements?

Hey all,

We are looking into purchasing a new Cisco router (ASR1001x-2.5g-K9) with a SmartNet service agreement (CON-SNTP-ASR105GK) for our library. We put together an RFP for companies that work with schools/libraries using E-rate (discount on stuff for education) and the quotes we received seem a little odd. So I started looking around and noticed that the price variance for this gear is huge.

For instance, I have seen the ASR1001x-2.5g-K9 for as little as $7K (on Amazon) to as high as $27K (random IT gear website). The quotes we received were all around $11K-$14K. Also, the price that one company quoted us for the SmartNet service (CON-SNTP-ASR105GK) was $8K but I've seen it sold online for $2K.

Are these companies just trying to rip people off by charging more and hoping that people are too lazy to shop around? What am I missing?
