Heey!
I've been living here about 4 years and I think they have about everything in Lebanon. And also stuff we don't have at home (diff food).
Only a few Swedish things,like specific food, I'll miss when am here, that I can't find, since they only have them in Sweden. But I can count the items on 1 hand...
Its hard to tell what's more expensive here then outside, you mean if ur eating out or buying cloths, furniture etc. I think the cloths and other stuff are as expensive as in my home country. Food from supermarket is slightly less expensive. Eating out is not cheap, if it's in a normal restaurant, on the other hand u can find cheap fast food places of many kinds that are cheap.
Best of luck!
