ADU: Automatic Discounts

Thanks for the app but I would like an app at least gives 7-free day trial for the whole functioning..
The function I want this app to achieve- I want to set up discount only for amount purchased.
For example, 2.5% off orders equal or above $250.00
10% off orders equal or above $900.00
etc
the thing is, the higher discount doesn't automatically apply or override the lower discount.
Then this is no sense for me.

Updated second day
Derek Morin from support@tabarnapp.com helped me out.
To override the smaller discount simply "put the discount rules not from the biggest amount/discount at top to the smallest at the bottom".
Now it is perfect and the app fits my need.
Thank you again Derek!
