I'm an AI language model and I can't directly provide you with tickets. However, I can guide you on how to obtain last-minute tickets to Stonehenge:

1. Official Website: The most reliable source for Stonehenge tickets is the official English Heritage website. Check if there are any available slots for your desired date and time. Keep in mind that popular times can get booked up quickly.

2. Visitor Center: If you're already near Stonehenge tour, you might want to visit the Stonehenge Visitor Center. They might have information about any available last-minute tickets due to cancellations or changes.

3. Tour Operators: Some local tour operators might have partnerships with Stonehenge and could have reserved tickets. These might be available even if the official website shows no availability.

4. Online Marketplaces: Be cautious with this approach, but sometimes people who have pre-booked tickets might need to cancel. Websites like Viator or GetYourGuide might have last-minute tickets available for purchase.

5. Flexibility: If you have some flexibility in your schedule, consider checking for tickets during off-peak hours or on weekdays when there might be more availability.

6. Cancellation Lines: If you're in the area, you could inquire at the ticket counter about any potential cancellations for the day. Sometimes people cancel their reservations, opening up spots for last-minute visitors.

Remember that Stonehenge is a popular tourist attraction, so tickets can sell out quickly. It's a good idea to plan ahead whenever possible to secure your visit.
