just out of interest how much veg can you fit into a box that small?
2kg taters, 1kg carrots, 0.5kg onions, plus x amount of 2-4 other types of veg (beetroot, broccoli, cabbage, cauli, leeks, mushrooms, parsnips...). That's the mid-sized box. We're continuing to use bags and larger boxes for smaller/larger deliveries.
Simon, thanks for the input. I hadn't considered Ikea bags - ideally we wouldn't go down that route as we (a charity) have environmental objectives which lead us to favour more sustainable products than plastic where possible. However, considering they're so cheap and re-usable, it's something I'll chat to my colleagues about.
Best cardboard box supplier I've managed to find is on Ebay - 350 boxes for £168. Next best is 1000 for £500.
