Frequently asked questions
Are seasonal sales worth running?
When the whole category discounts, not running one costs share. The question is usually how deep rather than whether, and depth is where the money is lost.
What is the hangover effect?
The period after a sale when demand is below normal because it was pulled forward. It commonly lasts one to three weeks and costs a meaningful share of the sale's apparent gain.
How deep should a seasonal discount be?
Deep enough to be competitive and no deeper. Matching the deepest discount in the category is a decision to have the lowest margin in it.
What is the alternative to discounting?
Bundles, gifts with purchase and free shipping all create an offer without cutting the headline price, which protects the price point for the rest of the year.
