Plastic storage boxes medium/ large (Malvern Link WR14)

Hi I do a lot of car boot sales selling many items for charity, as it's nearly the end of the 'car boot season' I need to pack unsold items away in rodent proof containers ready for next year. I store my items in a garden room so being plastic the containers give more protection to my items. So any storage boxes (with lids please), the type used under beds or garage/ loft etc would be appreciated Thanks
