Yeah but how much for 4?

Presenting the pricing as if it represents a bulk discount when it doesn't.

The only reason to do this is to trick people who can't do multiplication into buying more.

It probably once did, but they relabeled it.
- Yeah, but only for 1. There would still have been no saving buying 3 over 2.
  
  If original price was 9
  
  1 for 9
  
  2 for 18 (deal gives 2 off)
  
  3 for 27 (deal gives 3 off)
  
  If it was 10
  
  1 for 10
  
  2 for 20 (4 off)
  
  3 for 30 (6 off)
  
  Yeah but it was never that. Only the original price was changed with a sticker. The 2x and 3x were always as they were.
  
  I know. If the single price was anything other than 8, the other hard coded prices give scaling discounts.
  
  The adjusted price saves you money on a single one and removes the bulk savings. Kinda neat to me. Wonder if that was on purpose to make it easier to move stock.
  
  *Edit: hell, the actual way to look at this is you get bulk pricing without the bulk. This is pretty awesome and mildly interesting if anything.
  
  Does it though? The moment 2x is £16 , the cost of 1 shirt is £8. Therefore there’s no scaling at 3x. It doesn’t matter how much the starting price was or how much the later prices were, if the 2x price is £16 and the 3x price is £24. The cost of 1 shirt is only ever £8 if you buy more than one, meaning that any pricing variant over 2x is pointless.
  
  I'm assuming the £8 is a sticker put in the item and not what it originally said, since it looks raised and like a sticker.
  
  That leads me to believe the original price under the sticker is greater than £8, which makes the discount make sense. And makes it interesting because the lowest a store could set a single unit and maintain the price curve is £8.
  
  Exactly. In which case the 3x price is redundant.
  
  There is no curve.
  
  Well sure - they put one sticker on and it solved everything. Are you suggesting they should have put a sticker to adjust the price of a single item and then also put another sticker on to hide the 3x item? That's not only a waste of stickers and time, it also really doesn't add or remove anything from the situation.
  
  I'd argue you are the mildly infuriating part of this scenario at this point.
  
  But you don't pay more either. Without the discount on 3 pack, buying odd numbers would've been worse value than even numbers but the 3 pack discount makes all bulk purchases equal.
- It only makes sense they did if the origianl price was higher, which is quite weird unless they specifically don't want people to buy more than 1
- gotta jack the price up again to afford more price stickers.
I'd argue it's a nice thing to make the costs obvious for people who can't do multiplication.
You can clearly see there is a sticker over the original price. It originally probably was a bulk deal that the store reduced to an all around deal.

You're over here bitching about people who can't do math and you can't even see.
- I'm bitching? About people who can't do math? That's news to me. Thank god you were there to tell me!
  
  Oh, does "bitching" offend you? Would you rather I say "you are so prepared to be annoyed by something that you completely gloss over the facts in front of you so that you can present the situation in a negative light"? Is that better? Ffs, they LOWERED the price and you're over here spouting Big Capitalism Conspiracies®.
  
  I'm way more worried that there are people like you amongst us than I am of Big Sweater confusing me with multiplication. Maybe worry more about the education system if a tag like that is so confusing to you.
  
  I'm not particularly annoyed by the original post, I was just trying to be helpful and answer the question the other commenter had. Even then, this community is named "mildly infuriating" , you'd think being annoyed would be kinda the baseline.
  
  I will admit I'm a bit annoyed by your tone and approach to conversation, which is probably why my last comment was a bit snarky. I do apologize for that. However, I honestly don't have the energy to deal with people initiating a discussion with immediate aggression, especially when they decide to read things into my comments that aren't there. You should try engaging in good-faith conversation sometime, it's a lot less exhausting than jumping at people's throats.
