I have found that even 300 thread count cotton sheets are cheaper (or the same price) as in the States so I would not bother. What might be great is to get something that is hard to find here - like for instance a radio that has a hand crank for electricity black outs, or a flashlight that plugs into the wall and gets charged. There are little headlamps for walking about in the dark on sale at Walmart's for about $5. A circle of needles, and embroidery thread is a treasure - but mostly to my Haitian friends who sew. Pen knives - and nail care kits - wow- I had one that was in a box and cost me about $10---- it was a treasure.....
Let me see, I am just trying to think of all the things that I had which got stolen first!!
but you can get a coffee pot on any corner down here so it isn't such a spectacluar gift....

Flashlights with batteries are a great practical gift, plus extra batteries- great idea
a radio - yes
and the other ideas are good also.
I would recommend battery operated electronics, due to the lack of electricity there.
