ShopBack is having upsized cashback for Lenovo right now. 14% cashback with seemingly no cap on all devices. No expiry date/time stated.
Cashrewards also has upsized cashback but at 13% instead. Similar situation: all laptops, no cap, no expiry stated: https://www.cashrewards.com.au/lenovo
Update: Cashrewards has stated their 13% upsized cashback will end 23:59 on 30/11/2020. No confirmation from Shopback as of yet.
Edit: I bought a laptop that had a discount using the BLACKFRIDAY code and still got cashback. The cashback was also above $200 so this confirms the lack of a cap compared to a few days ago.
Is BLACKFRIDAY code included in cash back?
