Hello and welcome! 
To give you an estimate. For food: you can have a satisfying local meal for $10. If you are a fan of fast food there are many places like Texas chicken or Chester's, a typical meal would cost around $6.
Clothes: depends on which shop are you choosing, you can find really expensive ones here, like Levi's jeans for $55, or you can have a good jeans (not brand) for $20.
Alcohol: CHEAP! A miller beer would cost you $1.
Cigarretes: cheap too, a packet will cost you around $3 max.
Traditional Market: I don't suggest you go there, for shopping go to Majidi Mall, it's a huge mall with fixed prices, you can find whatever you need there, if you go to the local market they will probably ask double figures since you are an °µÍø½ûÇø. electronics can be found in Majidi mall for fixed and reasonable prices.
