I found a lady on eBay selling a set of Spideys. I won the bid and I see her location was about 5-10 miles away from me so I messaged her to see if she'd let me pick up the set. I picked up the books, she told me that the set was from her Dad's collection and she was in the middle of clearing his house, I gave her my number in hopes that she'd find more.
She texted me about a week later telling me she has AF15, ASM1-14. She gave me prices and I went to collect a day later.
This is all in the United Kingdom by the way
