Be careful with clubs offered at very low prices. Some of these offers are Chinese fakes that look almost identical to the real thing however when played produce erratic shots.
Amazingly there is a chinese fakes online shop! You will find a complete Callaway set; 9 X20 irons + 3 Woods + 1 Odissey putter + 1 bag + Glove, cap and balls for US$ 240 + shipping ?!?!
I've noticed that some offers on ebay actually use the pics from this chinese site!!!! just check the site hygolf.cn and compare the pics with some offers on ebay!
