Abandoned Cart Journey and Revenue Calculation

Also, this should be setup in a campaign not a canvas (unless the race condition issue with using the same event for entry and exit in canvas is finally fixed).

Historically, using the same entry and exit in Canvas created a race condition.  If you had 4 cart updated events, sequentially adding 4 items and inserted the cart items in the email, the resulting email would randomly have between 1-4 items as it would not always use the most recent event for messaging.

If you are not inserting the cart items and the cart URL is the same in all the cart update events, then you do not need to worry about this, otherwise I strongly suggest testing your canvas.
