I had an £11.95 item be offered as a business price for £1.
I have never set any business prices for any of my items. This is either a glitch/bug or Amazon changed the price details without warning. Luckily it has only happened on one of my items (so far).
This means I have sold 3 £11.95 items at £1 due to this price change, I did not notice the price on the invoice when someone purchased two the end of last week! It clearly has only just changed, or I would've had an influx of orders, I have never sold this design in all the years I have been selling on Amazon, suddenly it goes to £1 and I sell 3. So clearly this adjustment only changed this week.
I tried editing / removing the business price, but each time I went back to check the inventory it was showing the business price back at £1, so I had no choice but to delete that item.
I wanted to warn you all, as it could be happening to others items, please check your inventory.
