Yes, I recognise that there are pattern parts available, but I asked about the Dyson part, because that is clearly identifiable by those of you who are in the know. It is unfortunate that the sellers on ebay are less knowledgeable than they might be.
There is an ebay listing, offering an item, using the same picture as yours, for £5.95, as opposed to the Dyson part for £15.95, both p&p (to UK) included. The price for the pattern spare would, therefore, be less than half of yours, when the delivery charges are included and the genuine part would be only a couple of quid more.
Delivery to France would be great, if the French postal system was anything like as good as Royal Mail which itself, at times, is undependable. It is expensive and it can take two or three weeks to get something delivered from the UK to France, so it is generally better, I find, to get things delivered to our house in England, when it can take a couple of days up to, perhaps, seven.
All of that said, in the same way as I would prefer to buy things from a small, specialist shop on the street, even at a marginally higher price, because I can get good advice from them and, thus, better value for money, I would prefer to buy parts from organisations such as yours because, if we buy purely on price, rather than on value, we will lose access to properly informed suppliers.
Would you be prepared to negotiate on the total cost of either part, including P&P? That way, at least I would be able to demonstrate that I had achieved an improvement on value for money.
