I bought a DE razor to save money on blades. Since then I have bought Proraso Trumper Harris EJ creams 2 after shaves and three kinds of blades. Already looking at a second razor. So much for saving money on blades lol.
Buying one razor won't save you money, you need volume! If one razor saves you X amount of dollars then 2 razors will save you 2X amount of dollars. It's basic math.
Your problem is you don't have enough razors, blades and soap. I would also guess you are lacking in the brush and aftershave department as well. Once you start aquiring more of these items you will see your savings grow. Eventually you will have saved up enough money to buy this nice little bridge I have to sell you.
