SFP Cost Variation

[Nicholas Warren <nwarren () barryelectric com>]

Quick question for the experts.

Why when looking at SFPs, some sites list them as $800 when the same part
number can be found on places like amazon for $30-$40. What is the
difference in them? Why would I buy them from a place like CDW with what
appears to be a 2,000% markup.
