This filter compares the total amount of the transaction (including tax, shipping and handling fees) to the maximum purchase amount (the ceiling) that you specify.
The specified action is taken whenever a transaction amount exceeds the specified ceiling.
Important: The Maximum amount per transaction setting in the Account Security menu controls all transactions, even those that exceed the Total Purchase Price Ceiling filter.
An unusually high purchase amount (compared to the average for your business) can indicate potential fraudulent activity. Because fraudsters are not paying with their own money, they are not price-sensitive.
