The offers used to be organised by ‘offer rating’, however this means the order of the list is constantly changing. You could see a list of offers, click to page 2 and then some offers from page 1 would be on page 2 – due to ratings changing.
So we felt organising offers alphabetically made a lot more sense. It also means similar offers are grouped together instead of all spread out throughout the offer list.
Hopefully this makes finding offers you are interested in easier! :)
