I am by no means a mechanic or a professional repair technician. So by that standards I can only rate my experience. Recently GSF was running a promotion of 50% off online and I needed new break pads for my car below is my observations and I could be wrong on this. 1 online list price was higher then normal price as well as on counter price so 50% discount would not be true reflection of actual price 2 discount was only applicable to online list price my guess is as it was highly inflated to offer 50% discount 3 after quick calculations it works out I got item 12% cheaper then actual on the counter price 4 in order to get discount I had to place order online and then go again to collect it. 5 stock indicated on website did not reflect actual store stock I was told that although item was shown in stock in peticular store the store did not have the physical item there and was incoureged to order more expensive replacement. In short you might not get the discount you think is on offer and might end up paying more for item as the cheapest option will not be in stock. Effective marketing but not ethical or morally acceptable. As for break pads they work fantastic and can't really complain about the staff at the store.
