Logo design for a second-hand store named "Mercadillo Store". The style should be clean, modern, and slightly vintage, combining a sense of trust and warmth. Include a retro-style shopping cart or a vintage price tag icon. Use bold, rounded, and friendly typography. Colors should include warm earthy tones like terracotta, olive green, and beige. The background should be white or lightly textured like recycled paper. The design should be optimized for use as a profile picture on Instagram or Facebook.
