Love the good old carton currency, we got our cot, portable, bouncer and nursing chair from various people for carton payments! I used to fix mates cars for cartons too, tho havnt done much of that since about 5 months pg. Then theres bbq n beer payments for helping or being helped to move house or build something... We also swap eggs and veggies from the garden for stuff from friends gardens, between us all we can almost keep the crisper stocked (except for the cold weather fruit n veg) it's a great system!
