camping gear and tarp (Lower Weston)

Looking for a Green or camouflage tarp and some other camping supplies anything would be great full. I have a one man tent, backpack, mat, sleeping bag and gas burner attachment. But looking for possibility a army water canteen and pot, but anything will do just wondering if there are anything people are getting rid of bottles, plates,pots, head torch. Thinking of going camping but on a budget so any help would be great
