Dude or Dudette, I highly recommend that you switch to a safety razor instead of any disposable.
The blades can be bought in 100-pks, which will last you almost a year at two blades a week. I have a rough, tough beard so that is about my rate. A 'case' of 10 10-blade packs will run you about, oh, $20. That is, what, two disposable razors or about two packs of 5 blade replacements?
On top of this, the shave is so much more clean and comfortable. I get almost zero razor burn with a safety razor.
Your one-time startup costs will be:
- Razor: $50-90
- blades: $20
- shaving cream: $20
- brush: $20
I know it is a large chunk to bite off to start up, but only the shaving cream and blades will need replenished over time. If you get a good razor, it will be something you can pass on to your offspring.
A great place to shop is Amazon. You will get their suggested 3-item bundle pack suggestions, and you can get the razor, a pack of blades and the brush for about $50. Since you likely already have a shaving foam or gel, you can start with that, until you can get a good cream-based lathering item. I cannot recommend Art of Shaving products highly enough. Their shave creams are very good.
