I think you're referring to the blockchain transaction costs, and thus assuming each daily purchase of bitcoin is transferred on the blockchain. Another approach would be to accumulate bitcoin in an exchange account (off-blockchain), and withdraw the balance to your bitcoin wallet (i.e. on-blockchain transaction), on a less frequent basis, perhaps monthly. That would mean more like ~$990 invested.
