hi fido
your links are for unifit, the retail site of homespares, the clearence offers are on the trade site which you need to have a trade account to access, which you may have. I've been called before about clearence prices on bearings. I've just checked and the hoover new wave etc heaters are available for £1, then plus vat and postage, but you need a cash or credit account in order to buy them.
I generally wait until I need a few parts, then make up my order with clearence parts for the vintage appliance we collect and restore, in order to meet the value to qualify for free postage.
