Currys is currently selling the 10.5in iPad Pro (with 256GB) for £449, a monstrous saving of £320 or 42% from its RRP. This is by a distance the cheapest we've ever seen this product.
Amazon had previously been matching the deal - indeed it was a penny cheaper - but has now ended the offer. Act quickly if you want to buy before Currys ends the deal too. (Amazon's best option now is £384.99 for the 64GB model, but note that it's renewed, or second-hand.)
For comparison, here are the best current prices across a range of retailers for the less generous 64GB version:
It's important to point out that this is the 2017 model - the generation before the current one - and you should therefore expect it to become obsolete roughly a year earlier than the 2018 equivalent. But we don't expect that to happen soon: it remains a powerful machine and won't let you down.
