The jeans at the store were 20% off, unless they were the Slim-Relaxed variety, which were 30% off, today, but not tomorrow after 3:06 p.m. Everything else in the store was 15% off, except for the things you really wanted, but additional markdowns, varying from 10% to 60%, would apply to the sales rack. If I found a really ugly shirt they were ashamed of making in the first place, the markdown would be 140%, and I'd make money on the deal, but only if I opened up a credit card, in which case they would take an additional 10% off the price.
Next week, the sales associate said, everything would be 40% off a second item if you joined the Reward program and submitted to an oral swab to get your DNA in the database so they could tailor their promotions to your needs.
Every trip to this store is like this, as if the company's marketing director used to write middle-school math textbook questions.
