You are flogging a dead horse.
And yes those who know regularly suggest buying from local dealers but that is not enough to combat the selfish greed of the buying public.
The idea that every time you open your wallet there are reprocussions is totally foreign to most people, till they get made redundant or the kids/grandkids can not find a job .
The fact that big box stores force factories to sell them goods for less than the actual cost price so the local dealer can not match the price never come into mind.
All that is important is they got what they wanted for the cheapest possible price so they can brag to their friends about how smart they are and can spend all that saved money on beer and lottery tickets.
The big box stores sent Noma to the wall then sent Murray to the wall but who cares,,,,, No body.
If you need confirmation, just look at the ever increasing sales through Amazon & Evil Pay, both of which are destroying the economy but both are regularly touted as being a marvel by the press & the owners become the new economic messiahs .
