What should I do if I'm having Affirm or Paypal checkout issues?
If you've chosen Affirm* or PayPal as your payment option and you aren't being directed to their site, check your pop-up blockers first to make sure the site can pop up so you can log in.
If that doesn't work, try clearing your device's cache, try a different browser, or a different device. Technology can be tricky but often one of these suggestions will get the job done.
