1. It makes everyone wait for the sales, so suddenly your company is addicted to sales.
2. It makes everyone who bought before the sales wonder if they got screwed.
3. It makes everything cost more.
Read #3 again. The simplest sales model is one where everything is a fixed cost, no sales, no promos, no special package deals, no loyalty programs. And simple is inexpensive. Simple means we don't have to pass the cost along to you. Anytime we do a sale, start a promo, offer a package deal, or start a loyalty program, we're adding cost to our products.
That's why we have one price list, no discounts, no sales, no promos--because it passes the savings along to everyone.
