Any excuse to pen an article about breasts :o)
I love people who get upset about things like these.. the sudden realisation that the world might not be quite as fair as you thought, that not everyone is the same, and that your piece of cake isn't always exactly the same size as the kid next to you.
M&S is a store, they sell a lot of things, amongst them clothes. In this case; bras. As far as the price of materials, 'construction' and assembly is concerned, they do not charge separate prices for all their sizes (AA bras might need less fabric than a B, but there might possibly be more females among us who fall into the B and C categories than into A, D and others, so an AA might cost more to buy in than a B or a C.
The actual 'price' of making these things in the first place probably varies between each size, and its probably not a linear variation. Now, it would not make any sense for M&S to price all their sizes differently, as it would just confuse the customer and possibly cost them more in administration than setting different prices would. In this case however, it seems that M&S has determined that the price of making bras with cup sizes above D's incurs a cost that makes it beneficial to them to operate with two prices. It has nothing to do with the person who's breasts are going into said bra, but everything to do with economy of scale (how much its costs for M&S to get the bra).
Besides, as a former skinny person and presently slightly round, I think more girls with smaller breasts should take to the streets and demand cheaper bras, as theirs costs less to make (presumably) and they should therefore not have to pay more for them. Then in stead of marking up bigger sized bras M&S could just reduce the price of the smaller sizes, and everyone would be happy.
Until someone realised that the kid next to them had gotten a slightly bigger slice of cake than themselves.
Now, to find out why I have to pay more for my +6 prescription glasses than my gf who has +0.25's. It's an outrage I tell you.
Anon, as I am presently at work, and should not be reading the reg ;o)
