To post an ad in the For Sale or Pets category, you'll need to use Yahoo! Wallet to purchase a Yahoo! Classifieds listing.

If you don't have a Yahoo! Wallet account, you can sign up during the purchase or go to Yahoo! Wallet and sign up at any time. Simply follow the instructions and fill out the forms, and you'll be able to make purchases across all of Yahoo! using your Yahoo! Wallet.

If you don't have a credit card (or a debit card with a Visa or MasterCard logo), then you won't be able to purchase a featured listing in Yahoo! Classifieds at this time.
