Dell: Cashback 5%-20% @Topcashback AU

Looks like 5-20% cashback on Dell products

Unsure if it is capped, Guessing uncapped as there is nothing about it ( if someone could comment be helpful )

20% off XPS range and Alienware
5% off Monitors
6% Inspiron
8% G Series
8% Latitude, optiplex and precision

Also, Cashrewards is 15% uncapped i think?
Also, Shopback 5-22% capped
