Came across this this morning. Www.classicdressage.com is currently offering £20 off your second pair of pikeur breeches. I had been communicating with the owner regarding color, and she told me about the promo. Shipping for both breeches was £20, so basically shipping was free. I bought 2 pair of princesse (knee patch) breeches with shipping for $275. That is basically what they cost at the few tack shops that carry them here in the states. Might be worth checking out if interested. There isn't a code to out in, it automatically deducted it when I put the 2nd pair in my shopping cart.
Just want to put in info that C.D. has been great with me - ordered Cavallo breeches in the wrong size, and the owner was very quick to email me back and put the size I needed on hold until I sent them back and she will exchange them and ship them back for me for free. Owner is good with communication and with any issues.
