Background: on Cyber Monday I held some very limited time buy one get one sales. For example I sold our Earbags as buy one get one free between the hours of 7:00 PM and 10:00 PM EST. To do so I created a category discount:
- "discount by a percentage based on quantity"
- discount details "repeat|2-100"
I did this throughout the day with various items/categories including the same deal earlier in the day, but the evening deal had issues.
A few customers called because items were adding to their cart at $0 and in the checkout it showed $0 product, $4.95 shipping and a total of $144.95 (even though the total without any discount would have been $67.95 after shipping).
One customer left a voicemail mentioning these figures and I spoke with another customer with EXACTLY the same thing. She was kind enough to send me two screen shots. I can email those, but rather not publish them.
Any ideas what caused this?
