I apologize in advance for being a bit long winded, but hear me out here. You must have enrolled to the Amex shop small and Amex Click Frenzy statement credit in order to get the deal. As was addressed by robbo135 here, purchases from Under Armour qualify for both Click Frenzy and Shop Small statement credits. But what I have found is that if you add any of the items that is part of their Click Frenzy 25% off sale, you get 25% off not only for that item, but for every item in your cart, even if they are not part of the sale. But you must have at least one of those items for sale in your cart for the discount to be applied. Obviously the closer you are to the $60 mark after the 25% discount has been applied, the greater the discount in terms of percentage. And since your aim is to spend at least $60, you automatically qualify for their free shipping. Managed to score a couple of caps and a sackpack for about $23, when you factor in Cashreward's 6.40% cashback, so I'm quite happy…:)
Hope this helps someone, happy shopping!
EDIT - thanks to keano1989, it appears that you need to go through the Click Frenzy website (https://www.clickfrenzy.com.au/search/result?q=under+armour) to get the discount to be applied to the cart. Mod: Updated main URL to Click Frenzy outgoing URL
EDIT 2 - seems like they have fixed the bug, so that the 25% discount only applies to the sale items and not the whole cart…ah well, it was fun whilst it lasted…
I am having error message of "your payment was rejected, please try again" I tried 2 AMEX card both got the same message. Anyone experience the same?
