Okay, using the 3 for 2 offers, I've got:

Halfords Premium Microfibre Cloths (twinpack) - £4.29
Megs Smooth Surface Clay kit - £24.99

Megs Gold Class Shampoo and Wax twin pack - £16.99
Total £99.71Remember, these things will last you more than a year, maybe longer. Some won't last as long. My own shampoo is 250mls lasted me twelve months, so the 470ml in megs shampoo should last you guys much longer. Things like Fast Glass I run through quite quickly.
Have a loot at:

Example: Bilt Hamber clay bar doesn't require lubrication - you use just water, hence much cheaper than Meg's smooth surface clay kit. I ran what I would normally buy through one of the above shops, and even if you bought some items from halfrauds on their 3 for 2 offer, it still all comes to £100.
As I stated previously, it depends on how much you want to do yourself and how much you're willing to pay someone else. £100 to do something yourself, bearing in mind you keep the products forever and can use them regularly and most will last you more than twelve months, it can work out cheaper.
For those who want their car to look good with minimal effort, you can always get the car done professionally. It will cost aroud £150-200 but means you can get away with a simple wash (still using two buckets, a microfibre wash mitt and a shampoo), dry with a drying towel and either a wax top up or a detailing spray to act as top up. Would cost around £20-30 total and means you keep the finish looking good.
