Primark low prices & cognitive coherence

Today it was my first time in Primark.

I was firmly convinced that I would have never bought anything: two weeks ago I saw a Tv program about Primark… low prices… working children*…

I got in the bus with two big bags containing:
2 Pillowcases (1.50£)
1 Throw (4£)
2 Pillows (4£)
1 Duvet (4£)

How did I justify it to myself?
1) I'm unemployed at present (It depend on the situation - I'm different, it's not my fault)
2) What about more expensive goods? Is the higher price a guarantee of fair working? (I, and everybody else, simply can't avoid it - I'm like all the other)
3) In many rice fields children work hard and in very unpleasant conditions... and what about diamonds? (Same as above)
4) If we don't buy, how would they survive? (I'm a philantropist!!)
and so on and so forth...

Summary:
- Low prices are hard to resist.
- Assassins would never think about themselves like assassins

*During the TV program Primark communicated that they were completely unaware of working children in their supply chain, and added that they would have not accepted to work with those suppliers any longer.
