Various methods and systems are provided for conducting e-commerce. In one example, a method of conducting an e-commerce transaction includes a method of operating an online retail website. The method includes providing access to a computer interface for suppliers and presenting information to the suppliers through the computer interface regarding activity of the supplier's stock keeping unit (SKU).

The modification of the parameter may include, for example, modification of the presentation of the SKU including, for example, changing the title, adding video or photograph, or adding some other information. The modification of the parameter may also include, for example, modifying the price or entering into a bilateral agreement with the operator of the retail website.
