When a vendor has overstock, I guess the overstock is sent back to the
distributor?
I would like to know how I can buy this overstock, in bulk lots,
directly from the distributor or whomever is supplying the internet
stores. How would I go about buying overstock in bulk lots directly
from the distributor?

The distributor more than likely gets their products from dozens of
discrete sources, including:

--companies going out of business
--law enforcement disposal of confiscated goods
--industry auctions of overstock/discontinued goods
--fire sales
--unclaimed merchandise sales
--disposal of off-spec merchandise (e.g. misprinted CDs)

Can you provide me with a list, with contact details, of say, 10 of
the above such sources of distributors with overstock of small
products, preferably based in Ireland but it's not a necessity.
