837: Coupon Code

 Coupon Code Title text: This also guarantees he won't be one of the ones to get a bobcat.

Explanation

Some online stores allow you to enter a coupon code for a discount on one of their products. Coupon codes may be a single, simple word or a complex sequence of characters. In this comic, Cueball enters a long and detailed blackmail message in the normally short coupon code form, hoping that blackmail could serve the way a coupon code would. This works so well that Cueball is discounted the full price of the product he's buying. The humor comes from the fact that Cueball's intimidation works as if the online seller was an actual person, and not a computer.

The title text references 325: A-Minus-Minus; it has become a running gag that bobcats are occasionally sent by mail by Black Hat in various comics. How blackmailing a computer would prevent Black Hat from sending bobcats to random people is a mystery.

Discussion

If you see in the first frame, the Subtotal is a one-digit number, possibly \$3.19. Yet the tax is way higher, and the subtotal is higher still. Thoughts? --Kuilin Li, [email protected], didn't bother registering. 67.175.58.94 03:00, 9 January 2013 (UTC)

The word next to the (potential) 3.19 isn't 'subtotal', though. The first letter might be a K or R, no idea on the second, the third is probably an E, K or R again, a 'one foot' letter like I or T, a C (I think), another 'one foot', a round bottom like a C or O, then possibly an H. I'm sure it's a real word, knowing how much detail he puts in the simplest things, am pretty sure it's not 'subtotal', but no idea otherwise what it actually is. --StarChaser Tyger (talk) 03:59, 30 January 2013 (UTC)
My guess is that it says "AMERICIUM". —Tanner Swett 107.5.152.253 22:29, 22 March 2013 (UTC)
Hmm, looks like you could be right. Also, americium is a radioactive element commonly used (in tiny amounts) in smoke detectors. It's probably the only transuranic element you can find in your house. --Aaron of Mpls (talk) 03:46, 29 August 2013 (UTC)

I don't really get the joke: is it about the idea that stealing something from the house of a dying woman is a rather common thing to have on one's conscience? and Cueball tries to leverage on that everywhere he can? Or would it be that Cueball really knows who is on the other side and what he can pressure them on? - Cos (talk) 14:28, 7 February 2013 (UTC)

The joke is that coupon codes are normally bland, corporate, impersonal, and small (you don't save that much money generally). Also, they're now sometimes shared on sites like RetailMeNot. This is just the opposite. It's a highly profitable way of exploiting a personal secret the buyer knows about the seller. Mattflaschen (talk) 03:48, 9 February 2013 (UTC)
Highly effective way? Only if the buyer was reading the discount code input manually! 220.224.246.97 12:53, 21 February 2013 (UTC)
It's the romantic image that there is more behind the interface than mere, cold technology. But atleast a sentinent being, if not humans. I don't think there's an actual joke that is supposed to make you laugh here though. --91.46.105.142 22:11, 3 July 2013 (UTC)

It is way too specific to be a "shot in the dark", the extortionist clearly has inside knowledge. 108.162.246.117 01:01, 18 January 2014 (UTC)

Price of the product

I think the price is 3.14, as it is the closest number that matches with the image & perfectly divides into 65.94 (80.02-14.08). --ParadoX (talk) 00:58, 4 April 2014 (UTC)

That sounds like something Randall would do, since 3.14~=π . Z (talk) 20:35, 20 April 2014 (UTC)

Wish it worked in the XKCD shop. 199.27.133.36 06:08, 18 September 2014 (UTC)
