Just testing a simple single product "Buy Now" button in PayPal and finding that when clicking through to PayPal, PayPal will opt to show either one or other of two different "flavours":

There's this look: enter image description here

and then there's this look: enter image description here

Sure, I'm familiar with both, having experienced them both as an end user, and assumed it was down to the merchant's options or his choice of PayPal configuration.

But testing - now as a merchant - I'm finding either one will show, as I say at random. Don't get me wrong, either flavour performs its job. It's just a bit unsettling.

Do I need to be concerned? And why does PayPal do this?

From a bit more digging around, I believe these PayPal's terminology for these two themes are Classic and Enhanced. But I'm still no wiser as to when and where PayPal opts to show one or the other.

  • Is the first one because you're logged into PayPal already on another browser tab? Oct 14, 2011 at 14:23
  • @paulmorriss i didn't think so, but just to be sure, i double checked. logged out of paypal. just the same, i get the two flavours

It looks like they are doing A/B Testing. This blog article found that they were in 2010, so it looks very likely they are here too.
