Plastic or cardboard packing boxes (Tm2 TN2)

We are helping my friend move this week from London to East Grinstead. We need packing boxes for lots of stuff he's packing up. Anyone that has plastic or cardboard packing boxes for free, I will come and collect them whenever you want. Hopefully, it will be before Wednesday, as I believe Wednesday is the day we will be moving them, but if this post is still up, please reply.
