I think you should bring some good quality extra virgin organic shade grown coconut oil; you can sell it to other members of BAexpats for a loooot of money!
I have boxes of ZipLoc bags I brought from the States I didn't find anything particularly wrong with the ones I found here - except you could only buy a few in a package and they were exorbitantly expensive. For the same price (if I recall correctly) as I could buy a bag of 10 bags here, I bought a box of a hundred in the States...
It has been years since I bought ZipLoc here, or even looked for them.
