That's why I only bother to take books to Garden Centres (where if
there is a copy of anything RHS it's heavily sealed in plastic and
sold for full cover price).

IME, it's very unusual for any of the big GC chains not to have
reference books available to customers on request.
(staff copies are usually under the desk or in the back office; you won't
see them unless you ask).
