Should I wait for Black Friday (Germany) ?

I want to buy a TM2, and the updated version with ball stem and a free dosing capsule is available for 340€. Is this a good price or should I wait for Black Friday? How much does the price usually reduce at that time ?

Update: There will be a sale from 29th nov to 2nd Dec (asked them through email). Ordered it anyway as I was tired of rotating my Dynavap and getting inconsistent hits that take too much effort. My new tm2 be delivered tomorrow. Can't wait!
