Reasonable Cost of Supplying and Fitting Carlton 1 Florin Door

[bolo 2]

Got a catalogue, picked a replacement door and now want to know what sort of price to expect for supplying and fitting. Any ideas??

It’s a Hallmark catalogue but there are no prices shown. So it’s a Hallmark Carlton 1 Florin. Anyone know a rough cost of supplying and fitting?
