PayPal Newsletter Ads - Any Ideas?

[John Motson]

I just got the Aussie version of the PayPal newsletter (Father's day edition)
and interestingly they had a whole bunch of ads for Australian internet
businesses including easyflowers.com.au, sportingbet.com.au, catchoftheday.com.au
dinosaurdeals.com.au etc.

When I click on one of the ads I am taken to paypal-offers.com.au which interestingly
states:

Welcome! Here’s our selection of Big Brand web sites which accept PayPal, Australia's favourite way to pay online. Click on a logo for more information. Or simply browse by categories below!

I wonder if these are paid advertisements or does PayPal really select some
top sites and put them in their newsletter.

Anyone have any ideas?
