What crucial factors should I consider when comparing different Samsung phone deals advertised?

When comparing deals, consider the total cost (including shipping, taxes, and potential contract fees), the condition of the phone (new, refurbished, used), the warranty terms, return policies, any included accessories, and the reputation of the seller. Also, verify the specific model number and its compatibility with your region's network bands, and ensure the phone is unlocked if you don't want a carrier-tied device.
