I have a ton of stuff I want to ship back to the UK (I never use it, but I don't want to get rid of it, and it's just getting in the way). Where's the best place to buy shipping boxes and packing foam from?

in abu dhabi? go to any of the removal companies, ikea sell some, or go along to 6th st and see what you can find.

I'm sure you lurk on here enough to know the OP is in Dubai...

Let's travel all the way to AD for a.......few boxes.

FFS buzzer.

then put down boxes in dubai needed....!!! as usual did i get you off your backside to have a go at me again... whatever....

Try the shippers.

For Philipines LBC or arina do door to door deliveries, drop you off an empty box and for 250 dhs ship and deliver it.

see if crown / pickfords / whoever offer similar for UK.
