Enter the destination: Include the full address or at least the city and zip code.

Double-check the destination: Wrong zip codes can cause errors.
Consider dimensional weight: Some carriers charge based on size, not just weight.
Update your info if needed: If your package changes, recalculate.
These small steps can save you from paying more than necessary or facing delays.
