The price seems reasonable considering even inviting those 10 guys for the test and failing would cost 1 million.. and thats just 1 star masters, I imagine the rank 3 pill will need a 3 star to make it, or perhaps someone of peak 2 star who can get it after a few attempts. Those can probably be counted on 1 hand even at headquarters.
Like always everything is exaggerated. Everything loses logic. So one single pill costs 200k and other millions, and somehow the daughter of the city lord didn't have 50k nor their butler who has a high post. I was just waiting for the op to *f:#$ up the currency, from here forwards NOTHING involving money will make sense. I just want to you to remember too that some chapters before a top restaurant was considered extremely expensive for costing 100 gold.
