Super Walmart Center - Walmart Not the same price at all stores and they do not price match there own stores. Henrietta New York

Our son wanted a Nerf Vulcan for his birthday which we found at the Greece Walmart priced at $35 and change.  Being that I am with our children all the time and couldn't purchase it to surprise our son my husband offered to pick it up at the Henrietta Walmart on his way home from work.  He called me and said it was priced there at $41 and change. He located an employee and explained the price difference.  They informed him they do price match stores but not there own.  He then got a supervisor and still they would not price match even though the other store was another Walmart. Frustrated and angered my husband purchased it as not to disappoint our son for his birthday and left. After his birthday I was curious and checked the Chili Walmart and the price was $35 and change. This for me is not over as I am getting the receipt from my husband and going back to a Walmart and demanding the difference back. What is anyones thought on this? Will let everyone now how it turns out.
