They supply good quality parts at a competitive price. However to get the best price for the parts I need I have to wait until I receive an email from GSF advertising a discount code. This discount code is usually much better than the discount code available to me if I just access the GSF web site. But of course if I need parts I have to wait for a discount code which is not always readily available. This marketing approach is the same as Eurocar parts and I tend to compare both company prices. The GSF pricing and marketing approach is annoying but I tend to 'put up with it' but feel it's all a bit of a farce. I don't know why they have to play this discount game with regular customers and offer different discount codes. I would much prefer not to be messed about and have GSF offer fair and resonable prices on their web site and that's the price you pay and not be messed about with all these discount codes. Their approach is unprofessional in my opinion.
