The clubs will be a lot cheaper in the US ( although there are a few discount stores in the UK that get close on other brands if you keep your eye's open) but do be aware that you are liable for duty on anything over £250 (I think is the current figure), do be aware this is the TOTAL of goods brought back so clothes and trainers would be included. Whil e, in general, the customs don't seem too bothered by an extra £50 worth of clothes, if you try to bring back the pretty obvious set of clubs and choose not to declare them while there is a chance you won't get stopped, if you do they will know the clubs are new and may decide to go through everything else with a fine tooth comb. I know people who've successfully escaped detection, but I've also known people who've been stopped and found it a costly and embarrasing situation.
