Moving boxes (Jacksons Lane, Billericay)

I run the Billericay Terracycling drop off point. I send off between 50 and 100 kilos of recycling every month. Everything must be packaged in large boxes (the side used for house moving) My daughter moved 1 year ago and I am just beginning to run out of her boxes! If you have any boxes up to 60cm x 60 cm x 50 cm I would put them to good use. It's all done by volunteers for charity. Thanks.
