A discount as much/low as 80%

[Xinfu]

-In case I forget to tell you - if you ever go to the uni bookstore to buy anything, ask me for my premium card, which offers a discount/discounts as much/low as 80%. You can get discounts/a discount, and I can amass/accumulate scores; it is mutually beneficial.


Are my sentences natural?

Are my sentences natural?They're natural, but a little long for formal writing (too many commas). I think you meant 'points' instead of 'scores'.
