My name is John, also known as @RetroGems_, and I’m a UK-based reseller. I started my reselling journey towards the end of 2024 after discovering the reselling community on TikTok and seeing what was possible with the right knowledge and consistency.

What began as a small experiment — visiting a local car boot sale with £30 — quickly turned into a genuine side hustle alongside my full-time job. Through hands-on experience, trial and error, and learning from real sales, I’ve built a practical understanding of what works and what doesn’t when starting out.

I created this guide to help absolute beginners avoid common mistakes and get started with reselling in a simple, realistic way. Everything I share is based on real experience and focuses on building a sustainable side income rather than quick wins or hype.
