Amazon.co.uk offers the Harry Potter: The Complete 8-Film Collection on Blu-ray Disc for $34.41 (£23). At checkout, the price drops to $28.68 (£19.17). With $4.61 (£3.08) for shipping, that's the lowest total price we could find by $7, although we saw it for $7 less in December.

This Blu-ray set is region-free, and the films themselves will play on US Blu-ray players, but note that the extras and special features may not.
