I once saw someone sell this method on many forums, and someone really pay for that!! I will show how to do that here today for free :> 

If you have a Paypal private account, you will enjoy the free transaction of course, but if your papal account is business or premier account, you need to pay 2.4% to 3.4% or more service fee for every transaction. This fee could add up to huge if you use Palpal constantly! There is a simple way to avoid the big fee by using one of the Paypal service–’Mass Pay’, which most of the eBay and paypal users are still unaware of it.Ok, fist let’s have a look how Paypal say about Mass Pay:

Overview

Mass Payment allows anyone with a Premier or Business account to send multiple payments instantly—saving time, money and the hassle of having to individually send funds to every payment recipient.
Mass Payment can be used for such things as:

  • Affiliate commissions
  • Customer rebates
  • Pay-to-surf rewards
  • Employee benefits
  • Lottery prizes
  • Survey incentives

How do I get started with Mass Payment?

Start making payments by following these simple steps.

  • Step 1: Collect payee information
    Conventional check runs require three basic pieces of information: the name of the payee, the payee’s street address, and the payment amount.
    However, with PayPal’s Mass Payment, you need only the recipient’s email address and the payment amount.

  • Step 2: Create the file of payees
    Create a tab-delimited text file. List the recipients’ email addresses in the first column and the payment amounts in the second column. In the third column, enter the three-letter code for the currency in which the payments will be sent:

  • Step 3: Sign up for a Premier or Business account
    Create a Premier or Business account with PayPal, or upgrade your existing Personal account.

  • Step 4: Fund your account
    Fund your account by transferring money from your bank to your PayPal account. Credit cards cannot be used for Mass Payments. Your PayPal account must have sufficient funds to cover the Mass Payment and fees.

  • Step 5: Make the payments
    To make a payment, click Mass Pay at the bottom of any PayPal webpage. Next, click Make a Mass Payment on the Overview page. Locate and upload your Mass Payment file when prompted and customize the email your recipients will receive. Click Continue and then Send Money to instantly process the Mass Payment.

How do payment recipients get their money?
Payment recipients claim their money by clicking a link in their payment notification email. If they do not have a PayPal account, they can sign up for a free account to receive their money.
