Typically a coupon will be presented in the form of a coupon code. This will be a short code, in capital letters, that is to be entered at checkout in the field marked ‘Voucher/Discount/Coupon Code’. A coupon code may have a particular requirement associated with it, for example ‘Enter code 10OFF when spending more than $100 to save $10’. In this case using the coupon code on a basket of less than $100 would not trigger the $10 saving. A deal is usually offered by a retailer in order to encourage incremental sales on existing purchases. This is your typical ‘Buy One Get One’ or ‘Buy Two Get Three’ style of deal. It typically applies to retailers and is used to help clear existing stock towards the end of a sales season. A promo is usually a sitewide discount offered by a retailer for a given product, service or category. For example, ‘20% Off Holidays in Antarctica – Today Only’. Promos do not require a code to be entered at checkout. However, a promo may only be valid on a specific product or service so please do read the terms and conditions. A promotion may exclude certain popular categories of items, such as certain brands within a product category.
