Most gun & ammo collectors are no big fan of Ebay, or their payment processor, Paypal, due to their anti-gun / anti-ammo policies. Ebay has always been very strict on this, and has always banned ammo sales as long as I can remember, and even restricted gun part sales sometime in the early 2000’s. Lately however, I have noticed that ammo seems to be for sale on Ebay - quite randomly. Their policy has not changed, and as listed here it describes any components of, and any loaded rds, blank, black powder, or otherwise loaded ammo to be prohibited: http://pages.ebay.com/help/policies/firearms-weapons-knives.html.
Over the past several months I have noticed an increasing amount of what seem to be black powder cartridges, especially transitional era type loads which they don’t seem to mind (type “civil war cartridge” into the search engine), but just today I noticed this very obvious listing for 1000rds of new 9mm ammo, by a major seller: http://www.ebay.com/itm/9Mm-124Gr-Tmj-1000-Rounds-Remanufactured-Michigan-Ammo-Co-Case-/351122104301?pt=Vintage_Hunting&hash=item51c0821fed
The revision history indicates it has been an ongoing Dutch auction since July. The seller seems to be one of the automated mega-sellers which essentially grabs, re-processes, and re-offers other existing retail-website sale listings from the internet and just dumps it on Ebay at a slight upcharge, and the system runs itself just processing payments and acting as a proxy to purchase & forward the purchased item - in this case, live ammo.
I am left to assume that Ebay is not enforcing their own rules as fervently as they have in the past, or else is enforcing on a reaction-to-complaint basis only?
