Thank you for your question, Aptamil is a wonderful formula and all the other formula closest to ot are also in the same price range. You can opt for Similac IQ who is little bit cheaper but if you want much lower cost then ingredients will be compromised like nan pro, Similac advance etc. among these nan pro would be more similar to aptamil. You can choose that.
Next Steps
You can choice between Similac IQ or Nanpro
