One can only assume the manager said he could "not" price match both times. Otherwise the mirror would have been purchased and this letter wouldn't be here.

*Asking* if the store could price match is completely understandable, and it makes sense that it would be easier for the customer to buy the mirror from the same place as everything else.

However, once you are told "no", the answer is to buy the product from the place that sells it cheaper. Not berate the manager for "insulting your intelligence."

Furniture shopping is difficult and time consuming. If you gave up purchasing several items over not wanting to buy one of them next door, you must have a lot of time on your hands.
