greggs has an ample saddle test program but i believe they don't allow returns on parts that have been installed. (torque, thread integrity, etc makes me not want to buy a previously installed and ridden part except at a discount...)
parts that have not been installed are returnable. most cyclists have extra, ridden stems laying around if they don't know what length stem they need. its the nature of the sport. get a fit or try different length stems. if its installed on your bike, it's your part.
if you think they don't let you test and return any saddle they carry, you havent asked about testing a saddle.
i don't know how strict their policy is about test rides.
