Yeah, I know others have had problems with Sheldeez customer service, but I have order from them twice in the last 8 months without any issues. I ALWAYS compare the two sites before ordering (those are the only 2 sites I'm aware that sells affirm relaxer system) and I would say that while Irby's *products* cost less, the shipping charges really added up and indeed when I comparison shopped both sites for the same items and included shipping, sheldeez was a bit cheaper at the bottom line so it's worth checking out, keeping in mind some others had issues, and some like me, did not (yet . . .)
