Third-party online shopping feeds can give you access to new customer universes

Cost

Costs for shopping feeds varies slightly from site to site, but there are two basic models: the cost per click or conversion model (similar to paid-search models), and the percentage-commission model. Shop.com and Amazon, for instance, charge commissions on each sale made through their sites. The commission level is determined at the outset of your partnership with the shopping feed.
