I'd like to express my view on the way sales are advertised. I'm commenting on the current sale of TDOT, but I think this is relevant for all recent sales.
It seems to me that the savings should be advertised as the difference between the regular price ($699) and the discounted price ($549). In this case this sale offers a savings of $150 or 21.46% off the regular price of $699.
By advertising the savings in relation to an irrelevant price ($975*), we're likely to think we are saving more than we are. If I had bought this at regular price ($699) and my friend bought it during this sale, he would not have saved $426 (43.69% of $975) compared to me. Rather, he'd have saved $150 (21.46% of $699). The percentages really confuse me since they are what I look at first.
I've learned that I must do my own math, since I don't consider this method of advertising to present reliable and relevant information.

(*To the best of my knowledge this is an irrelevant price. I guess it might reflect the cost of the paper edition or something like a "list price", but I don't think it's a price that is normally charged for TDOT in Accordance, and this price doesn't have a "name". We don't know if it's a "list" price, a "paper book" price or what it is. If my terminology is inaccurate ("irrelevant"), please don't be offended. I was just seeking a way to express this using terms as neutral as possible.
