To activate a card, you have to choose a dollar amount you want below, if all the Cash Cards in the amount you want are redeemed then choose another. The Cash Cards are available in the following amounts $10, $20, $50, and $100. Then you  log into the PayPal My Cash Card account, and load the funds directly into your PayPal account using the PIN number in your email (you will be asked to enter an email address after you complete an offer into which you will receive your Cash Card PIN). If you haven’t got a PayPal account, you can create one at this time here. After the funds are loaded, you can checkout with PayPal at any of the online merchants’ websites where PayPal is supported.
