I ran into a nice piece of Defensive/Contingency Design today on Amazon’s site. Here’s what happened… I placed an order, then placed it again because I forgot to use a $25 off coupon I had. My plan was to then cancel the first order. But, Amazon recognized that I just placed the same order twice so they wanted to check to see if that’s what I really wanted to do:
I know it’s cut off, and shrunk a bit, but is basically says: “Jason, you placed an order for these items a few minutes ago. Are you sure you want place the same order again?”
This is great Defensive Design — making sure I really wanted to do something unusual like placing the same order twice. Well done, Amazon.
