The description as a 'second issue' makes it sound legit and if the ill-informed were in any doubt about it being a legit release they would probably think well it £150 it can't be a bootleg can it.
It like the supermarkets doing offers of 3 for £5 and having the same product somewhere else in the store at £1.60 each. Price is a surrogate indicator of quality / value and marketing people know this.
A fool and their money are easily parted, just as it's always been.
