THREE-YEARS-OLD AND STILL ON SALE

Is it right that one of Bangkok's top bookstores is selling a three-year-old edition of Tropical magazine in one of its prime positions?
On the plus side, this particular edition of Tropical contains 'timeless' content that is still relatively attractive today, and at 50 baht it's a 50 per cent discount from the original cover price.
But when space for new titles is understandably limited surely it would be better to have a more timely title in this slot?
Several copies of this magazine have been on sale in these slots for more than three weeks now. That says all you need to know, in my opinion. It didn't sell three years ago and it's not selling now.
