PSA: VERY YMMV (check emails): Got a $5 “A Special Gift to show our Appreciation” Email from Best Buy (might be for inactive accts)

Not sure if it was just to me- but I got a unique email code in an email titled "A Special Gift to show our Appreciation"
I dont actively use this account so perhaps its tied to that (check junk email). I did not have it on my main account. YMMV!
