Next trip is in few days, InshAllah.
Yes food items are mostly need, Since you are in Karachi why dont you buy yourself and give us the stuff, we will deliver it.
Mostly we do our purchase from Imtiaz Store, they give us a very good discount.
All the basic stuff rice, milk, daal, tea, etc are packed in 1 bag for a family to last atleast 15 to 20 days so he does not have to look for donations and carry on with is work.
I will be going to Imtiaz Store in a day or 2 to do more purchasing, if you want you can come with me...
