In Finland there are small biodegradable plastic bags available in grocery stores. Free of charge. They're mainly for vegetables, fruit etc. Downside is that they are weak enough to break if mishandled. Bigger bags to hold all your purchases - made from recycled plastic - are available from the cashiers for 20 cents. Edit: Regular small bags are also available free of charge.
