Without going into detail - I'm noticing that some Professional DSLR lenses are on sale at amazon for up to 50pct off. An example would be an L-series lens which sells for 2200 being available for 1180 - again, that's an example. I'm not promoting Amazon or offering any links or giving you real pricing..
When this is the case, are those lenses about to be discontinued. Should they be avoided? I normally see them at consumer electronics stores for the high price. Is there a service or a database where users can post the lowest prices that they've seen for equipment?
(just added this) As an example, please see http://www.amazon.com/Canon-100mm-2-8L-IS-Macro/dp/B002NEGTSI/ref=sr_1_1?ie=UTF8&qid=1365521688&sr=8-1&keywords=canon+100+macro+2.8l+is
It's at a huge discount...but in line with Best Buy's price...makes me wonder if they just boost the MSRP sky high, knowing they will actually price it considerably lower.
