oh no don't worry there are cost, just that they are all relative to each individual needs. Overall, because everything is being imported, the result is that everything is expensive... Except the product who are usually sensitive to taxation in other countries, like alcohol and cigarette. Basically anything bad for your health is cheap and everything good is expensive LOL!
It's also depend if you are going to receive salaries in Euro, or in US $...
I don't know about Kenya, even though I did lived in Africa too, but here books (novels) are about $10 each at Gd Marche Supermarket, and music CD's are about $20 each. Gas is about $5 a gallon (maybe cheapper in some gas station on the French side where they will take $1 = 1 euro, but they do not all do that...). Food is relative... a bottle of wine is in average between $5.5 and $12 depends what you like, and that's about basic wine. You can find way more expensive if you want. Food depends like the rest on your tastes and your needs. If I compare with my sister who also live here with her family, she is spending much more money than I do on a monthly base, because I beleive her taste are a bit more "extravagant" than mine. I am sure that if you come to visit for a week or so before coming to live permanently, you will have a chance to visit supermarket and books store and make up your own judgement based on your personal tastes and needs.
Like I said
