We just returned from Negril about a week ago, I didn't find the beach vendors any more aggressive than in the past. There are definitely less tourists on the beach than in previous trips, so I think you are more of a target. I always buy a bracelet or two just as a good faith purchase, and I will look at crafts etc. as I walk by or that I have promised to return to. I tell the Ganja guys that I already have what I need, that seems to work most times. Looking doesn't cost anything, just don't let anyone hand you anything. I did see some outright begging this year and I tried to give a little bit if I could, times are tough. Once you say no a couple of times, to the regular sellers they will not bother you (as much)
