The sign reads:
WE HAVE MODA FABRIC"
Now, one might think that the "0% OFF" is a mistake. Surely it was meant to say "20% OFF" or "40% OFF" or "70% OFF", and a digit simply fell off the sign.
But when a person - like my friend Dwayne, who told me about the sign - drives by that sign every day for over a month, and the message has not changed, and the store is still in business, one begins to wonder what other reasons might lie behind the "0% OFF".
POSSIBLE REASON #1: The store is using "0% OFF" as a quirky surprise that will catch attention, pique curiosity, and attract customers. "After all," thinks the passerby, "no store in their right mind would offer '0% OFF' as a legitimate promotion. I wonder what they're doing in there. Maybe I'll stop in and see."
POSSIBLE REASON #2: The store is using "0% OFF" as a one-size-fits-all promotion. Customers realize that "0% OFF" must be a mistake, but that there must be some sort of sale going on inside the store. The store doesn't have to change the marquee to "20%" or "40%" or "70%" based on the discount of the day; the same message can remain on the board and still achieve the same effect.
POSSIBLE REASON #3: The store is using "0% OFF" to make a statement. The store is saying that their prices are so reasonable, that they don't need to offer discounts. Customers don't need a discounted price, because this store's prices are already the lowest in town. This store's regular prices are as low as their competitor's sale prices.
POSSIBLE REASON #4: A digit really did fall off the sign a month ago, and the store owner hasn't noticed, and the store manager hasn't noticed, and the employees haven't noticed, and no customers have said anything. Or someone did notice, but they ran out of extra numbers for the sign, and keep forgetting to order more. Or someone did notice, but they haven't taken the time to change the message yet - in over a month.
Whatever the reason for this particular marquee message, the goal of outdoor messaging is to draw customers to the store. Logical dissonance (i.e. "that's strange" or "I didn't expect that"), price discounts, and "everyday low prices" can all be used to raise customers' attention. Of course, all three tactics should be used strategically, and should be crafted with the customer in mind.
"What will the customer think?" and "How will the customer perceive or understand this?" should be two primary questions when crafting one's marketing messages - or any other marketing tactics, for that matter.
Your marketing message should be clear to the customer. If the customer thinks that your message was a mistake (i.e. a digit fell off your sign), he is going to keep driving right by.
