Being creatives doesn't excuse us from being familiar with basic principles of economics — especially when they intersect with social psychology. The scarcity principle states that humans ascribe higher value to products with limited availability. Create your own scarcity by, well… just saying that your product is scarce. Pointing out that your product regularly sells out is a double hook — it implies that others see value in what you sell while working as a silent “BUY NOW BEFORE IT SELLS OUT AGAIN!” CTA. Basically all this ad does, aside from offer a couple of product explainers, is tell you that you’re lucky to even be graced with the opportunity to buy it. Hard bargain from Soft Services.
