Right now a pack of ten Machx blades lasts me about two years cos I can't be arsed changing them every time they stop causing cuts hence blunt. A six month old blade does a reasonable job and causes my skin less irritation than a new blade.

Specifically Mühle razor and Derby Blades (€10 for 100)
After a learning curve: never looked back. This is my tip of the day on CUK.

- Printer manufacturers:- The printer cartridges cost them next to nothing to manufacture but still they have the audacity to sell at a huge markup.
I'll just connect it up with a piece of string, shall I??

I cant find a UK article but I'm pretty sure they have contact lenses in the USA The 12 Biggest Ripoffs in America
And in first place... I think we're going to have to agree to disagree on this one.

I'm loving this. A thread on an IT contractors board complaining about the difference between cost of raw materials and sales price.
What percentage of your montly invoice does that HB pencil and the pad you nicked from the staitionery cupboard make up exactly.

I just can't see how you think a tub of popcorn is more labour and material intensive than a pair of contact lenses? I could get some corn an make popcorn now, I'd need a processing plant and expertise to make lenses.

I've watched part of your YouTube vid and that does look like a labour intensive and piece-by-piece affair, however Wiki suggests most contact lenses are mass produced in the following ways:
Of course special or personalised lenses are a different affair. I'm speaking of bob-standard lenses of a certain prescription, diameter and curvature being mass produced without any particular person in mind. Such as the ones I buy.

Having visited Bobland (Bangalore) and seen some of the standards of hygiene around there I'm not sure that I'd want my contacts to be manufactured there.

I don't want to be picky but why focus on the storage liquids when thats one of the lowest cost parts of the process?
I've watched part of your YouTube vid and that does look like a labour intensive and piece-by-piece affair, however Wiki suggests most contact lenses are mass produced in the following ways:
* Spin-cast lenses - A spin cast lens is a soft contact lens manufactured by whirling liquid silicone in a revolving mold at high speed.[31]
* Lathe turned - A lathe turned contact lens is cut and polished on a CNC lathe.[31] Lathe Turning is #101 of Mass Reducing Operations.[32] The lens starts out as a cylindrical disk held in the jaws of the lathe. The lathe is equipped with an industrial grade diamond as the cutting tool. The CNC Lathe turns at nearly 6000 RPM (revolutions per minute) as the cutter removes the desired amount of material from the inside of the lens. The concave (inner) surface of the lens is then polished with some fine abrasive paste, oil, and a small polyester cottonball turned at high speeds. In order to hold the delicate lens in reverse manner, wax is used as an adhesive. The convex (outer) surface of the lens is thus cut and polished by the same process.
* Molded - Moulding is used to manufacture some brands of soft contact lenses. Rotating moulds are used and the molten material is added and shaped by centrifugal forces. Injection moulding and computer control are also used to create nearly perfect lenses.[33].
* Hybrids

The costs of the liquids used for storing contact lenses isn't all that high, even when paying massively marked-up prices for it.

I don't want to be picky but why focus on the storage liquids when thats one of the lowest cost parts of the process? When I said 'hydrating properties' I meant the lens, I use ones with high water content which cost more than standard.Last edited by gingerjedi; 4 March 2010, 14:26.
