[Bug]: Entering an invalid promo code makes cart appear empty

[michaelbromley]

Expected Behavior

When entering an invalid promo code, the cart should be unaffected. Probably an error message should be displayed somewhere though.

Actual Behavior

The cart goes empty, but refreshing the page reveals it to not actually be empty.
