According to TechFlow, Arkham revealed that MEV Bot 0x12F used only 0.05 ETH (about $100) to purchase $37,000 worth of COMBO tokens.

This operation was possible because an unlucky user had just sold $37,000 worth of COMBO tokens in a very illiquid Uniswap pool and received only $27 in return. To ensure that the transaction was included in the block, the MEV bot paid the block builder a fee of $30,000.
