It's a brilliant plan. We'll sell you bolts that rot and cost us peanuts. You'll buy good bolts from us at even greater margins. When the cheese heads turn out to be made of real cheese you pay us to get the extractor bit out. When you've finally had enough and trade it in we'll give you a rubbish price against a new one that has the same rubbish fasteners.
It's the best plan for repeated sales of rubbish since Wun Hung Lo told his customers to stick their poppy seeds in their pipes and smoke it!
