SC Sales Motivator

We geared our entire holiday sales around this app + 2 others from BOLD & all 3 failed us miserably. Free products would be added to the cart about 50% of the time. NOW after I've turned off the "goals" they're still rolling in with customers who have doubled up on discounts... yesterday's & today's discounts together. Literally costing us thousands of dollars this holiday! Just based on our experience needing it to work properly for ONE DAY, I would avoid at all costs! (Especially if you run a very big online shop & have a lot to lose if it doesn't work properly!) We are not looking forward to the headache this app has created for us today.
