I don't know what part of the country you're in, but in Northern CA, Peace is often one of the roses offered in the plastic bags at nruseries rather inexpensively - under $5. I know these roses aren't well-regarded (they're called body bags), but I planted the bush last year, and although I understand it's slow to mature, it's doing well. I also found the climber at Grocery Outlet for around $4.99. I suggest asking for recommendations from nursery managers. Any retailer who has the plant may offer you a discount. If they don't offer, asking is very appropriate!
