1Password got me with this. I was getting it for free because my work used it, but when I left, write/autofill was suspended. I had planned to move to a different service as I dislike 1P8, but I was in a hurry to just get things working again, and $2.99 a month is cheap enough to get me by for a few months. I enter my CC details. Get charged $39.47 (10% for GST). I go back and look at the site and realise the monthly price is billed annually. I don’t recall being quoted this price when I entered my CC details, perhaps it was displayed in a way that was easy to miss for people in a hurry. In any case there’s a dark pattern in their checkout flow. It’s disingenuous to to advertise $2.99 and bill $39.47. Imagine a cafe that advertises the price of their coffee as 40c then in smallprint “times 12 made in a single payment”. The advertised price should match the billed price for all products and services.
