Yup, it's something of a dark pattern by many companies. They make it as hard as possible to see what the final cost will be until you're deep in the order process. Oops, if you're dealing with something that never has extra costs and thus doesn't have a final cost stage to ordering it wouldn't be hard to imagine someone actually ordering when they intended to get the final cost. Likewise for shipping time. I need it by X and will not order if it's going to arrive later. That one isn't as much of a dark pattern as it's rarely done for deceptive reasons.
