Long story short, yes I do plan it out.
Over the past nine months I've been using the same razor for a month. It's definitely helped my shaves, not swapping around so much. I'll probably keep at that.
Soaps wise, this month I'm using the soaps I haven't used for a long time, and that I also don't have containers for. Once they are used I'm going into an makers name alphabetical rotation, as best I can. Obviously where I've more than one from that maker, I'm switching them based on the product name, to avoid using the same type more than once in a row.
