I **always** wait for 11/11 if I am to purchase anything big like a wheelset or groupset and when there is no rush or upcoming build.
I don't remember the prices for that group particularly but what I bought was lower in price + coupons were stacked on top and I landed some pretty sweet deals. I bought XT m8120 brakeset, 8100 groupset, Elitewheels wheelset and many, many small items to hit the coupon threshold.
This time I am eyeing 105 R7100 12 speed mechanical groupset after missing out some excellent deals earlier this year. That particular group has gone up in price since and has stuck there. Oh and a CSC gravel wheelset is in my cart too. Besides these, regular assortment of small goodies, fishbone cable housing, rotors, brake pads, inner cables, bar tapes, chain rings, titanium screws etc etc.
