I was browsing through the orders of the past few days and noticed something interesting in the way our users enter our coupon codes.
You see, all our coupons are always published written in all uppercase, e.g. “CLZTWEETZ”, “GETORGANIZED”, “GOOGLER”, etc… But our order tracking system stores the coupons exactly as entered. And scrolling through this list, I found that for most coupons, users enter them in all lowercase (e.g. as “clztweetz”), indicating that they typed them manually (as opposed to copying/pasting from our emails).
With one exception: the coupon we give to all our trial users: ITRYB4IBUY
