You can sell individual items on your site using your PayPal account and a button directing your readers to the PayPal payment screen.
You will need to log into your PayPal account and get a link code. To do that, you’ll first need to follow steps 1-9 on this page: Get PayPal Button Code. When you’ve done that, click ‘Next Step’ below.
Copy the ‘Email’ link that PayPal provides to you in step 7 here. Make sure you choose the ‘Email’ tab, or the code won’t work with your WordPress.com site.
Your link code goes between the quotation marks where it says ‘YOUR-LINK-HERE’ in the code provided below:
<a href="YOUR-LINK-HERE"> <img src="https://www.paypalobjects.com/en_US/i/btn/btn_buynow_LG.gif" alt="Buy Now Button" /> </a>
You’ll want to copy the code above, with your link in the ‘YOUR-LINK-HERE’ space, to be ready to paste it into a post or page in the next step.
If you’d like to use a different button image, you can find a few image options by scrolling down to ‘Button Images’ here, or you can create and upload your own image.
To place your PayPal button on a post or page, you can paste that code into the ‘HTML’ tab when creating or editing the post or page.
To display your PayPal button in a sidebar or other widget area, add a Text Widget in your Customizer, and paste your button code into it.
Save your changes and check your site, making sure to click the button to test whether the PayPal link leads to the right place.
