I don't know, I never spoke to anyone. I registered an online account with them, then searched until I found the KX500 rollers, picked my color choice, added it to my "cart"...then hit "Check-out"...and paid with pay-pal. The whole ordeal only took 10mins.
There was never any note stating whether that particular roller/part# was in stock or not...so I'm assuming it would be in stock...because you'd think that I would've gotten an e-mail or note upon Check-out, stating that roller was on back-order or something, but I never did.
The last thing I want to do is dispute it...I'd rather get what I ordered, and then just call it water under the bridge.
