Amazon UK offers Jurassic World on 3D Blu-ray / Blu-ray / Digital HD for $5.06 (£4.05). Add it to your cart and the price drops to $4.22 (£3.38) at final checkout. With $3.85 (£3.08) for shipping, that's $5 under our mention from November (which included a DVD) at least $10 less than you'd spend for a similar version (which also includes a DVD) at a local retail store.
This disc is region-free; the movie will play on US Blu-ray players, but the extras and special features may not. It ships from the UK and should arrive in three to five weeks.
