In the middle of last week a friend in New York told me, my book was for sale in B&N.
Tonight I decided to check- forget it-there is NO Al Place nor my book, in a post someone sent me last Tuesday, they said the store front was a nightmare to navigate. Having tried it-I have to agree. On Amazon you can find the book in seconds.
As for loss of sales when they go down- I will NOT miss them, as I don't think anyone would get to the book without a PhD in Electonics
