Ultra Necrozma GX

With only 2 UK sellers in the market, pricing matters—the cheapest is listed at £35.00, well below the £40.86 figure, so you'll need to be sharp on valuation and ready for a slower shift. Raw copies have actually sold for £45.31 over the past 90 days (3 sales, latest at that price on 12 Sep), which puts that £35.00 ask in interesting territory: either genuinely keen to move stock, or the asking price doesn't reflect what the market will bear.

• CautionOnly 2 UK sellers, cheapest at £35.00. Thin market: price firmly, expect a slow sale.
