THe products are more expensive that your drug store ones, so wouldn't buy them all together if you don't need them. I'd start with the shaving cream and if you have issues that are corrected, go ahead. I think you're supposed to use EITHER the powder or spray, so I'd opt for the one that seems ideal to you. Really, you could just get one of the aftercare products and use the shaving cream that you already like. I actually rarely pair beauty products like that, and there's a lot of quality shaving creams on the site you could use instead/
I'm tired. Hope this makes sense.
