I want to put my dead Xbox 360 warranty box inside it with my package inside which is 8 pounds. I don't live near a UPS store, but close to a dropoff box. Is it safe to put my package there? With these high gas prices, I don't want to drive all the way there. Also, I don't want to spend extra money with calling the UPS truck to pick it up. Is the dropoff box safe? Or should I go the safe way and just drive the extra miles (12) to the UPS store. I just don't want my box to get lost.
