Mr. Rooter Plumbing Ripoff by Parts marked up 421% and 528% Roswell Georgia

 I'm not going to get into the exact percentages because it doesn't matter....but there are some thing you need to realize.

First of all the "retail" price is what ever price a store sells an item for.  Say I want a TV.  I can go to 5 different stores and come up with 5 different "retail" prices.  It is MY choice as to which store I buy it from.  In your case of course you could have gone on your own and buy the $36 and $93 item.  But you didn't do that, you choose to let them sell it to you at their price which you failed to ask what that price was.

Well what would have happened if you bought the $36 and $93 item on your own.  Do you expect the plumber to just stand around free of charge and wait while you head down to the store and pick up the item?  Perhaps you were going to reschedule them when you got the part.   But then let's say that you got them to install the parts you bought, and a day later the part goes bad.  Do you expect them to come out for free and take care of it.  NOPE..they will charge you the same labor rate to remove the part, wait for you to go exchange the part, and install it a second time.   Because unlike had they sold you the part they are under zero obligation to cover the labor to replace the part.  Yes, all of these costs are built into the price you paid.

They had every right to call the police.  Oh and one little more warning.  If you are thinking of stopping payment or disputing the charges, they have the legal right to put what is known as a "Mechanics Lien" on your property.  If you don't know what that is..go look it up you may find it very interesting.

In short

ALWAYS get an estimate of what you are going to pay

Don't expect to get DIY prices from professional plumbers, mechanics...etc.

The same smart a-- I spoke to on the phone. 

You should have requested an estimate instead of assuming the price. Merchants are not required to sell merchandise at retail price.

$36 increased to $190 is a 428% increase, NOT 528%. $93 increased to $387 is a 316% increase, NOT 417%. That should make you feel better.
