found out the info they sent me, turns out it wasnt team dynamics
but a company which supplies their wheels and many others called rimstock.
Ive checked their website and cant see any discount prices so you will probably have to give them a ring. On the top of the sheet they sent me it says 'team dynamics deals of the month' so they may do discounts on other ranges of wheels.
The phone number on the bottom is 0121 525 6500 (uk)
This month they dont seem to have many 1.2 left so you may be lucky to find the right size/offset you need - the 17inch 1.2's are £37.50 each without tyres.
Good luck
