We can recommend Stripe as a very modern and easy to use payment gateway, with no setup/monthly fees (just transaction fees comparable to PayPal), which will allow buyers to simply pay you directly with their debit/credit card -- see our setup instructions for Stripe here:
Once you've done that, you can remove the PayPal checkout button from your E-junkie shopping cart. From your E-junkie Dashboard go to Manage Seller Account > Edit Profile, click More Payment Options, untick the box to Show PayPal in shopping cart, then click Submit to apply changes.
If your site is using E-junkie Add to Cart buttons, those will automatically pick up these changes, so you won't need to update those in your site. However, if you've been using our Buy Now buttons (instead of Add to Cart buttons), those use a predetermined checkout method that you'd select when you copy the Buy Now code, so you'd need to replace those with Buy Now buttons for Credit Card checkout.
