Look at the old and new price of .net of the image
What I'm saying is that yes, the image suggests that the "sale" is actually the same price as before. But sometimes there are mistakes make in postings on a website. So even though the website shows no difference, perhaps there is an actual change,with a discounted price, that they failed to upload to the website for the sale.
Sometimes, a company may be grateful for pointing out a mistake--either way. If it's not a sale, they probably would just as well correct their site. This astute original poster noted the curious posting, and probably the company would prefer to fix that as well.
