Table: prodExtra

Columns:
    upc int or varchar, dbms dependent
    distributor varchar
    manufacturer varchar
    cost dbms currency
    margin dbms currency
    variable_pricing tinyint
    location varchar
    case_quantity varchar
    case_cost dbms currency

Depends on:
    products (table)

Use:
Don't add to it.
As of 20Oct2012 it is still used by item/productList.php.

Deprecated. This mess dates back to trying to stay
lock-step with the Wedge's products table (which didn't
work anyway). The thinking was "Need a new field? Toss it
in prodExtra". Multiple, purpose-specific tables that
can be joined against products on upc would be a much
better solution.
