I do $1/piece or $5/bag (I provide a ton of plastic shopping bags). If people are careful, they can get a lot for $5. I place these in bins labeled Boy ages 0-2 or Girls 3-5 or whatever I have that yard sale. Special items (i.e holiday clothes, snow suits, etc.), I rubber band together (if multiple pieces) and place a separate tag on these (i.e. $2-$8) and place in a separate bin. It alleviates some of the, "Do you have this size?" or "Do you have any...?". Most of my kids clothes are Gymboree or Children's Place or Gap (but I only buy clearance items from the previous year when on sale and with a coupon or reward points from the stores, thus, I make about 1/3 -1/2 of what I spent back and other's are getting good quality items for much less than they would spend retail.) Most people will spend a $1 for good quality items!
