In the context of this discussion, that's actually very funny.
Surely the issue isn't about bodging, it's about an honest reflection of material costs.
So in a nutshell, this is your summary justification for hugely inflated markup on whatever product?
Seems a smidge ironic when on your own company website it clearly states;
'We are a Small, focused and friendly specialist operation that believes in achieving the best, not making a quick buck.'
Shifting back to the product in question as you seem to have a better appreciation of its sum parts than others, would you be willing to give everyone an honest and unbiased breakdown of the individual material costs for us please?
Item by item should be fairly simple I'd imagine - from memory there's the silicone hose section, a 90 degree breather joiner, a generic foam filter, a couple of jubilee clips and a bracket right?
Thanks
