I've been buying a load of "Woodworm" golf shirts recently. I thought they were cheap in the AG sale at £15.00 each but some on this site are only £7.99 or so. All of the ones I have purchased have been A1 condition (not seconds) and fit great. Good quality too. They do all different makes (Ashworth etc) and are a lot cheaper than anywhere else I've found. You have to be lucky to find the right colour in the right size, but their stock changes daily so if they haven't got exactly what you want today, look again tomorrow, it may well be there.
