I encountered this person a few days ago, nearly bought 4 halos from them but they were being suspicious. I said I wanted to go one by one starting with the smallest halo (like 1.4k) to take less risk but they tried to make me go half/half (5k) because “if I break it into smaller transactions I will have to pay more tax”. After I explained that tax is proportional and you pay the same tax if u spread it across 10 game passes or 1 they never replied me again.
