Second, the notion that this is hostile to the user just bemuses me. I don't understand why this has any detrimental effects on the customer. If they are fine paying full price (as they were when they began checking out), they are free to pay full price. If someone with expendable free time would rather dig through these coupon sites, that is their prerogative. The existence of a coupon code field merely gives the option to seek out a discount. This is similar to most other forms of commerce. If I have free time and want to save money, I can dig through circulars and clip ads, or I can just go to the store and pay full price. Is it offensive to the user that the self checkout also has a slot for placing coupons? No one is forcing anyone to do anything. How is it bad customer service when a user literally isn't forced to do anything other than ignore the field if they so choose? Giving people the option to save money if they are willing to exert some effort is an unequivocal positive aspect of most sites.
This piece is just incoherent to me. I honestly don't understand why this is bad in any way.
