Never had much luck with clubhouse for discount codes but never been let down by their service.
Golf support are local to me and always been great from new drivers, new iron sets to limited release putters in terms of their service. Have to google their discount codes though as their bespoke to manufacturers or specific items etc
I don't. Bought a set of irons from them this year, customer service was poor. The clubs were the same price on a number of sites, spoke to a sales guy at CG and asked if he could beat the price. He said no, but he would throw "some balls" in to sweeten the deal. Clubs came, no balls. Phoned them up to complain, they sent me a sleeve. Thought that was pretty tight of them tbh, told them that, not interested.
