Again the main points;
1) The power to purchase lies with the customer and is NEVER with the lhs or anyone else,
Agree, but for some reason lhs battles among themselves for customers. LHS A talk bad about LHS B. cust go to LHS B, seller talk bad about LHS A. so cust decision no buy as both sell problematic cars... then when cust go to LHS C, the owner talk bad on LHS A & B, so LHS C sapu the deal. the LHS A & B became frust cause put so much efford.. only kena sapu.. 
2) The lhs depend on the customer to survive and the customer don't have to buy RC stuff to survive.
Rc is hobby for past time. There are other sporting activities customer can look at.
3) If the hobby becomes expensive and customer pok-kai, lhs will also pok-kai. If customer happy and buy some more, lhs survive/untung more. LHS untung more, benefits will come round to customer(usually and you lhs should know if you are doing this or not ). This is a vicious cycle that is unfortunately the reality.
Customer pokai, no problem they can sell away their goods. like quiting rc sales. This will adversly affect the lhs sales. cause buyer can get real original item at least 1/2 to 3/4 of lhs price. not forget plenty of spares to dispose as value add...
