I'm in the HVAC business and I know that if you buy say a Honeywell thermostat from Lowes or Home Depot it is not the same quality as the model I will buy from my supplier.
They uselower grade parts to build those t-stats in order to be competetive.
Where I can see, but the average consumer can't. It also shows in the warranty where the big box stores thermostats only have a 1 year manufacturer'swarranty and mine have 5 years!
Maybe the debate could be settled by asking a licenced gun dealer/gunsmith evaluate the exact same model guns bought from 2 different locations.
1 from Wal-Mart and 1 from an independent gun dealer and tell us the differences in what we're getting.
