Here is BestBuy response:
Thanks for sharing your point of view regarding our recent ad, which included a wish for a “Happy Eid al-Adha”.

Best Buy’s customers and employees around the world represent a variety of faiths and denominations. We respect that diversity and choose to greet our customers and employees in ways that reflect their traditions.

We do use the word “holiday” in some of our advertising because it is meant to be inclusive to everyone. However, just as we have in the past, we will also reference specific holidays such as Christmas, Hanukkah and Kwanzaa in our weekly ads, store signage and other advertising vehicles.

We encourage our employees to interact with customers naturally and feel free to wish them a Merry Christmas if they are celebrating that holiday.

Thanks again for your feedback.

Thanks for your response. With a point of view such as yours, it would have been wiser, to leave off any salutation at all…since you were not wise, I will purchase my electronics from a store that has the “balls” to say Merry Christmas (a salutation used for years) and not shop at a store that bows at the alter of apeasement and political correctness…I will pass your response and my response to everyone I ever emailed.
Thank you

Best Buy has lost my business for good! I’ll only shop at stores that will honor the Christmas tradition….
‘Bye Bye, Best Buy’!!!!!

MY FAMILY AND I WILL TAKE OUR BUSINESS ELSE WHERE!
MERRY CHRISTMAS TO ALL AND HAPPY HOLIDAYS TO YOU HUMBUGS
ONE NATION UNDER GOD!

I THINK THE government SHOULD INVESTIGATE THIS,IT’S NOT NORMAL FOR AN AMERICAN BUSINESS TO DISPLAY THIS!I GUESS THIS IS POLITICALLY CORRECT HMMMMMMMMMMMMMM,TO HELL WITH YOU

I have been a customer of Best Buy for years but never again will I cast a shadow on a Best Buy store. Oh yes, I am sure you will continue without me but you can not survive without all the Bob Smiths of the world! How could you show such preference for the Muslim Faith and make mockery of Christianity? Do you not care they have killed thousands of our people and plan to kill more? Shame on your management, shame on your employees that continue to work for you and shame on your shareholders for owning a single share of your stock. Not anohther cent from me!!

I have been a long time customer of Best Buy but never again will my shadow darken the door of your stores! How could you coddle the Muslim Faith while you make a mockery of Christianity? Yes, you will survive without me but you will not survive without all the Bob Smiths of the world. Shame on your management, shame on your employees that continue to work for you, shame on any American that holds a single share of your stock. The sooner you take bankruptcy they better off we will all be. Bob Smith
