Design a vibrant and dynamic Instagram Reels image (1080px x 1920px) that represents a WhatsApp group dedicated to exclusive deals, discounts, and promotions. The image should feature a smartphone displaying the WhatsApp logo, surrounded by shopping bags, discount tags, and glowing percentage symbols (like -10%, -20%, -50%). The background should be colorful and exciting, with a mix of greens and yellows to evoke the feeling of savings and urgency. Include text that reads 'Join our WhatsApp group for unbeatable deals!' with an arrow pointing towards the phone screen.
