If ordering from a UK store, please note that you are in Region 1 (DVD)/Region A (Blu-ray), whilst the UK is in Region 2/B, respectively. This means that many - but by no means all - may fail to play. Look for products marked "Region free", "All regions", "Region 0" or "Multi-region". Blu-rays may also be marked "Region A/B/C", or variations thereof. You may also check whether your DVD/Blu-ray player supports multi-region playback (also referred to as "region free"), or whether it can be set to do so. There should, of course, be no problems with books, CDs, or other physical items.
