For 3,500 CFA (aprox $7) at the market in N'Djamena today I purchased:
-1 head of lettuce
-1 Green bell-pepper
All were locally grown, which is hard to do in a desert. If I had bought these items as part of the fresh produce flown in weekly from Paris they would have cost three times as much! Surprisingly the prices I negotiated are similar to what I was paying in a grocery store back in New Hampshire, especially if you consider these would be considered organic and cage-free items. Sure, others could have negotiated better prices but this was pretty fair. Now I have to soak all this in bleach-water since I still have a "delicate constitution" from only being back in Africa for just two weeks.
