I'm going to CSA for the first time next month. ( =) 4 more weeks!! ) I'm trying to get away with only bringing a carry on bag. I always get worried about my luggage getting lost.... But I know I'm going to need lots of sun screen and bug spray. Is it that much more to buy in Jamaica? Is it worth just waiting till we get there to buy it since i'd be saving $20 or $25 by not checking my bag or will it be a lot cheaper to just buy sunscreen and buy spray at home and check my bag?
