Founded in 1995, eBay is one of the oldest and most popular online auction websites. Since acquiring PayPal in 2002 eBay has integrated the payment website into its services as an easy-to-use means of payment. Even if an eBay user has two different eBay accounts, he can still use a single PayPal account to send and receive payments for auctioned and purchased items.
Creating Two Accounts
The eBay terms of service allow users to create multiple eBay accounts provided that certain rules are met. Each account must have a unique user ID and have a different e-mail address associated with it. Once created, the accounts aren't allowed to interact with each other on the eBay website; users found using two accounts in conjunction to increase bids or otherwise artificially inflate the cost of auctions can have their accounts suspended or banned.
Paying with PayPal
PayPal can be used to pay for most eBay purchases as long as the seller accepts it as a payment method. PayPal users can send payments for their items using the eBay checkout system or directly from their PayPal account to a seller-provided payment address. PayPal can be used regardless of which user ID the item or items being paid for were won with; if the payment is being sent directly through PayPal then the account doesn't even need to be linked to an eBay account.
Being Paid with PayPal
When selling items on eBay you can receive payments in your PayPal account even if your account is associated with a different eBay user ID. Your PayPal account must be linked with the user ID for your eBay seller account to use PayPal as a payment option on your auctions. Any PayPal payments you receive for auctioned or sold items will be deposited into your linked PayPal account automatically.
Linking Multiple Accounts
You can only link a single PayPal account with an eBay user ID, but you can link up to eight user IDs with a single PayPal account. On the "Accounts" tab of each user ID's "My eBay" page, click the "PayPal Account" link to access the PayPal information page. Click the "Link My PayPal Account" button and log in to your PayPal account to link it to the user ID. You may then repeat this process with your other eBay account using the same PayPal account.
