How did I find how much I spent since 2010? Good question - I was looking in my account so I could update my credit card information - As I wandered around the account information I clicked on something that brought up the total. I did not note where I found this, I just thought it was interesting.
Looking at my account to see if I could find the answer I did see that under YOUR ORDERS you can call up year by year for orders where all your orders for the year are listed. It is not what I found earlier but it may help you.
Havent figured out how to get report yet but quick guess says weve likley spent north of 10000 a year on average for last 10 to 12 years
