There is a sheikh "blah blha blha" charity (no offence meant but cant remeber his name!) that has a drop off hole in the wall for clothes etc. Location is at Souq Al Ali side of the Immgration (Al-Gharraffa) R/A (flyover).

Basic directions - coming from TV R/A direction go straight under Immgration flyover and do a u-turn at next R/A. On appraoch to Immgration flyover take the last slip road entering souq Al-Ali and there are a number of villas on your right - you WILL SEE the sign for this charity on the wall of the 1st or second villa.

Good luck
