Pricing Inconsistencies at Supply Houses

What happens here

The contractor agrees with the convenience argument and adds that sometimes tradesmen might actually pay more at a supply house than at Home Depot. He then highlights an issue with supply houses' pricing: they often have inconsistent pricing across different branches due to internal competition. He gives an example of a three-gang box costing $12 at one branch and $15 at another. If a customer complains, supply houses often cite 'different regions' or 'different branches' as an excuse, which the contractor dismisses as 'bullshit'.

Goal: Expose the problem of inconsistent pricing at supply houses.
