Hi there, Jacquie--
I'd like to add voice to what arcoiris says: the churches do a great job of distributing things to people in need. I served as a mission volunteer based out of La omana for quite some time and did alot of social outreach and distributions.
Bring clothes, sneakers, underwear [all of these things for all sizes and ages],bed linens, OTC medicines-- especially vitamins, pain relievers,cold preps, and first aid supplies. Anything made of denim and sneakers are hottest, but pepole accept anything from America as "golden".
Most of all, bring yourself with an open spirit.
Dee
