I gave my Travis 4's to my brother as a gift because he told me how much he wanted them. He ended up selling them to my other brother. Still kind of mad about it.
Don’t want to jinx it, but slim/none chance they cancel. I think once an order is placed with them you are good. They don’t really have the manpower to go around cancelling folks who hit on two pairs. I’ve done it before and they shipped.
I got an email for a pair of Grey Fod, but I checked those out in about 2 minutes. I placed a large order for clothes and it's pending on my CC, no email for that.
