If i buy a copper ingot for 10$ make it into a short blade, smack a grip on there, how does the copper only get marked up to 11$? Usually, if you are doing business you want to make it up at least 100-200% profit above of the original price you bought it at (ex: copper ingot sold at 100% markup as copper short blade for 20$). Is there a way to make this into the game because there is no real way to get up into the tiers of ingots (100,000$?!).
Do you understand business?
I worked at a small hardware store for 10 years and we had a similar price structure. For low cost items (under $5 cost) the markup target was about 100%, so a $3.00 cost item would sell for $5.99. In the business world you use a different formula so the percentages don't get as crazy. We calculated Gross Profit Margin which gives a percentage between 0 and 100. Formula was 1 - Cost/Retail, then multiply by 100 to change it from a decimal to a percentage. So if an item sold for 100% more than cost, it had a GPM of 50%, and 200% more than cost had a GPM of 66%.
And Ideally for Items below $20, you'd aim for 50-60% GPM. More expensive items (over $100) had worse margins (sometimes only 5-10% GPM) because people compare prices more when buying those items.
So the tldr version is: 100% markup is not uncommon for low cost items in the retail world.
