Edwin Watts or Special Tee have Big stores all over the place.
My friends and I have bought several sets and individual clubs from the Big Special Tee on I drive down past the Mercado. Don't pay the price on the sticker, they ALWAYS deal, also their VERY experienced in writing receipts for UK customs purposes, if you know what I mean.

Also its cool test the new clubs on their indoor range
Warning I,ve been stopped by customs EVERY time I come back into the UK with my golf clubs, never had a problem but its a pain, probably something to do with my brilliant red Wilson pro bag cover, stands out a bit
Another place for the odd bargain ( got a great set of Mizuno clubs a third of the UK price) is the Sports Authority ( 192 and up by the Fla Mall).
Theres a golf discount outlet store up on I drive past Wet n Wild, they sometimes have some bargains in amongst the end of line stuff.
And believe it or not, K Mart and Wal Mart often have "special" sets on sale, my DW got a fantastic full set of Wilson clubs and bag etc for $120, £200 over here!
