You stated...
here we have a buyer, and a seller. The seller has danced around issues that the buyer feels should be answered.
Apparently you never worked in retail. The seller was very straight forward..and offered a refund as per the policy...to the letter.
The government cards are not valid anymore..so even if BestBuy was to be able to have the government send the card back..it is expired and not worth the postage stamp.
So in this case..what has BestBuy done wrong or to dance around? The Poster is just upset that after a cheaper different brand box was found "somewhere on line" after the purchase of the box from BestBuy..which only cost the "Buyer" $16.04 out of pocket anyhow...why would BestBuy be responsible to return a government card that is not only invalid..but could not be used even if it was returned. The Buyer owns a 56 dollar box and 40 dollars of it was paid buy the taxpayers..I would be very happy with that deal.
Now if the customer can find the same model part number box for less..BestBuy would match or beat the price as per their policy. They will not match on-line prices as who knows what it is or where it's from when you order online. It could be a refurb, used, or break in 5 minutes..."On-line" does not have overhead like a BestBuy retail store..so there is NO way any retail store can or would ever guarantee to price match from "somewhere on line" and expect to stay in business.
