When I placed an order on Amazon recently, I was taught a very important lesson about how they process your orders. I made a rather large purchase on Amazon, as opposed to my usual $10 to $40 purchases I usually make. This one was over $1000 and I put it on the credit card that I have with the lowest interest rate. My plan was to pay it off in two to three months and end up paying the least amount of interest possible, but that's not what ended up happening. My credit card company declined the purchase, flagging it as suspicious. I don't blame them. I had recently gotten the balance on that card down to $0 and now suddenly there was a charge of over $1000 on it from Amazon. That would be a red flag for me too, but the thought never crossed my mind when I placed my order.
