sorry to keep beating this $30 horse but I sent 4wheelparts an email the other day stating my dissapointment on their 'bait and switch' sales tactics. It's ok to substitute if they aren't offering a specific BRAND item, but what they did was just poor business practice.
anyway, the next day I received a phone call (at work, no less) from someone at 4wheelparts who left a voicemail message and said that they did send the yellow one to me 'just in case I needed one for vacation or something' and that I was still on the list for the ProComp brand strap when they come back in to stock.
Now I'm SURE I never would have received another strap had I not said something to them, and I'm still have doubts that I'll ever get one in the mail from them, but it sounds like they know they got caught and are trying to cover for it.
