Pathetic Service

I went to purchase a hp 562 black ink cartridge at game galleria shopping center. I had a price beat from a online store and 2 supervisors said that they cannot beat the price of the online store as they were given instructions from their senior managers yet game pavilion were price beating online store prices. This is contradicting game itself. SO IS GAME STORES MISLEADING THE PUBLIC WITH THEIR STATEMENT THAT WE BEAT ANY PRICE. THE PUBLIC DOES NOT KNOW THIS
