For a couple of years I have used a Bosch mower and was very happy with its performance but I was finding it difficult to get the correct type of replacement blade through the usual sources (e.g. B&Q, Homebase etc). They were quite happy to sell you a complete mower but to find the right blade for a mower you already had from the selection in-store met with a "Try this one, it may fit" type of response. And when you find out it doesn't fit you can't take it back as you have openend the packaging.
This one fitted the bill perfectly and at a price that was in line with what I would have paid in any of the above stores - that is, if they had one to sell me! Not a saving as such but I got the blade I needed and at a good price.
