This set of three Jamie Oliver Knives have been reduced from £25 for the set to only £6.99 at Argos. Although the original selling price is high, these are still £11.99 on Amazon currently, and have never been this cheap.
The set contains a Chef's Knife, a Paring Knife, and a Utility Knife. They are stainless steel hollow ground blades, and are dishwasher safe. There's only one review on the Argos website, but there are lots on other sites including Amazon, and these are very positive.
You can't get the Jamie Oliver Knife Set delivered, but you can Reserve and Collect for free from stores, and stock seems very widely available.
