Even though this is a good deal, there is also a better one, which is to buy the London Pass on the official London Pass website using the London Pass promo code for a 55% discount off London attractions.
Let's see why..
With the promo code you can buy a 1-day, 2, 3, 6, or 10-day pass.
So, even though the 4-day London Pass is only available at Costco, you are better off with the promo code, by either getting a 3-day pass at a far lower price (£112.50, about $138) or, if you need more days, a 6-day pass which costs $177 (£131), still less than the Costco London Pass, but has 2 more days.
In addition, by buying the London Pass on the official website, you can download it directly on your smartphone with the London Pass App, which is then shown at the various tourist attractions included.
