Does sound like an expensive starter kit. Interestingly on the link, the blurb says "The expert kit to perfect the art of the traditional wet shave at home. Contains: Shaving Cream (200ml), Ernest Shave Brush, Ernest Double Edge Razor", yet the picture doesn't show a brush, and obviously you don't have one. The retailer's stock image and description basically don't match up.
Fair enough if you're enjoying it, but if that's basically a DE89 rip off razor, their equivalent black smooth handled DE razor sells for £26. Meaning you paid £84 for some pre shave oil, shaving cream and post shave balm, oh and a tin, and don't have a brush. Good that you're enjoying the DE experience though
