APC raw denim is not in the tbs sale. the cheapest you'll find them is at TBS, bit only when they do the once a season flat rate (I think it was 30 euros) discount codes. They come in at ~125 shipped to NA.
I treated them with a light layer of Obenauf's LP when I got mine. Didn't really darken them too much, there's pics in one of the red wing or obenauf threads of a pair before and after a treatment of obenauf's.
The difference between how fast fades set-in and/or develop after no wash, the first, and the second wash is pronounced. The difference between your jeans right before and after you do those washes is not.
