Got scammed by a shopkeer

So, I came to Delhi along wih my family for 2 weeks, booked an airbnb with a kitchen. They did'nt have a pressure cooker so I went to the nearest market to buy a cooker. A found a random kitchen appliance shop, wanted to save money on it as we were'nt planning to stay here for long. The shopkeeper seemed genuine. He offered me a 5L cooker for 1400, and said that he would take it back after 14 days and return 50% of the amount. I got excited accepted the deal and came back home. Just tried searching the net and found that the same cooker was for 600 rupees MRP. 🤦🤦🤦 I felt that I am the most STUPID PERSON to ever walk on the face of Earth. The way he presented the whole deal I don't know what happened to me but I could'nt refuse.
