Show all discounts at checkout with Craft Commerce I've taken the difference between the actual price and sale price of items and created a variable to hold the total value to give me a total discount at my checkout. I am curious if there is a way to do this with less code though? If I try to show {{ cart.totalDiscount | currency(cart.currency) }} it just comes up as $0.00, and this is with promotions -> sales at 10% off for all products. If there is a simple snippet like the one I referenced I'd love to know about it. Thanks!
Hmm, something else is at play here.

I use:

{% if cart.totalDiscount != 0 or cart.couponCode %}
  - {{ cart.totalDiscount | currency(cart.currency) }}


...and it works.

Are you sure the promotion is actually being applied?  I guess it is if you can calculate the discount.
