answer:Ah this is an old, old, very old trick that is often used in the retail industry. For some daft reason, there are lots of people who think that $99.99 (or in my case £s cause they use the same trick here) is oddly closer to $99 than it is to $100. Once you know that trick, you are never fooled by it again! I think it’s been largely responsible for the amount of rush purchases made in the retail industry that provide much of a company’s profit. And they think us lowly shelf-stackers don’t know squat!
