From what I've seen JW has a mix of devices to claim the "never knowingly undersold". One is getting models made by brands as an exclusive to JW. You can't find cheaper if it's not sold elsewhere. The others they do seem to cost more from what I've seen. You do pay extra for 2 years warranty.
Assuming you meant JL...the partnership did away with their Never Knowingly Undersold policy almost 2 years ago.
If they don't have what you want, buy elsewhere, you mentioned them originally.
A lot of the manufacturers sell direct. Don't forget to check Quidco and the like. You also work for a big corporate - many (like mine) have company discounts/cashback schemes which are worth checking once you've chosen a product/retailers
