So I was just generally browsing through ebay at booster boxes and saw a legendary collection booster box. I’ve made a thread in the past about how the price of these boxes have increased, however this box is listed for £1000.
The same seller has a few other boxes here: www.ebay.co.uk/sch/esmi2612/m.html?item=191275233792&hash=item2c88e47200&pt=UK_Collectables_TradingCards_RL&rt=nc&_trksid=p2047675.l2562
Looks like a case of showing off his collection as opposed to actually wanting to sell.
