Dusty - Reasonable price for getting oil change. Assuming ShitFit did it properly.
Tunnie - oil around £12 and filter around £4 on TC
Not when you buy a box of 20!
Yes it is. TC price is a shade under £4 + VAT for this filter. Not that you would know seeing as you never bought one, and nicked my spare 
I have a box of 20 of them in the garage (down to around 12 now)... I am sure i only paid £20 something for the box :-/
I'll bet a left gonad that you didn't buy 20 GM cartridge type filters for around £20. Never in a month of Sundays. TC price is around £4 + VAT each, so at best, 20 will be £60-£70...
...and added to that, seeing as you only have 1 car that takes cartridge type filters, you wouldn't buy that many anyway.
Keep seeing £4 mentioned for an oil Filter.
Trade Club price is still £1.22
2.6/3.2 and all diesels are more exspensive.
