  1. Click on the "Sign In" link on the Google Base homepage.
  2. Click on "Post an Item," click the "Choose an existing item type" dropdown menu, and select the item type ("Products" or "Vehicles").
  3. Fill in the fields on the "Edit item" page. The more relevant information you include, the better we can match searches to your item.
  4. Click "Edit" next to the Payment header and select the "Google Checkout" checkbox, which tells us that you to include a "Buy button" on your hosted page enabling customers to use Google Checkout when they buy from you.
  5. At the bottom of the page, click on "Publish." You'll be asked to sign up for Google Checkout. If you don't want to include your bank account information immediately, that's okay; you can provide this information later.
  6. You'll receive an email when someone buys your item.
