Thank you for your question, Cici! All Delta products with the same model number will be the exact same product in both appearance and material, no matter where they are purchased. Prices are set by dealers, so they can vary widely. Our faucets are made with a high quality standard and come with a Lifetime Warranty (Touch2O and Temp2O products have a 5-year warranty on electronic parts). We do utilize high grade plastic in areas that are prone to corrosion or rust to ensure the longest lasting product possible.
Best regards, Edward
