Hi Keith,
I worked at that original Livonia location in 1987! I truly appreciate your longstanding business with NPD. But please understand that NPD has over 100,000 active part #'s, spanning 12 catalogs that re-print throughout the year, and over 1,000 active suppliers.
There is no fathomable way that a salesperson could look at a random list of parts, and know specifically if anything on there has changed-price since the printing of the catalog. That would require a memory and recall like the Rain Man (certainly beyond my ability). And if you decide not to buy anything due to price, we have no problem nor penalty for unwinding the transaction.
Again, we have no intent to pull a "fast one" on you, or any of our customers. Our straight-forward no-gimmick approach over the years (no fake "our-price" prices based upon inflated/invented/baseless retails, no seasonal sales that are paid-for by charging inflated prices during the off-season, etc...) is hopefully evidence that we do everything we can to be straight-up and ethical.
I think the primary issue here is that whomever helped you at the counter earned a D- (at best) in tact and information. I will relay your experience to my Sales Manager and Store Manager there in Canton, and apologize that this wasn't better explained to you in person.
Also, I will mention that we are furiously working on the 2nd-edition of the Chevy truck catalog, with over 1,000 new items going-in to better "flesh-out" our selection. The first catalog came together like a hurricane, fast and wild, and with the second one we're wrapping-up a ton of details that got blown-past in the first.
Any shortcomings in service or quality, I'm anxious to know about. So Keith, please know that I'm not upset by your posting, and I'm grateful for the opportunity to discuss it.
