Who know a place where I can get stacking chairs at a good price?

Try Linens and Things. I used to work there and they had nice ones for about $15 a piece.

try a resort liquidation center. sometimes they are made a little better. and are also a little cheaper. it is kind of a hit and miss. also some of the model home resale centers. they sale all the furnishings off from the model homes if they do not sale with the model. you can find some great buys. i work in the retail market and sometimes some of the stuff they sale off cheaper than we can even buy it. we had sold one mantel to a builder for 379.00 and they sold it for the builder for 69.00. the customers who came in looking for a second one were quite amassed. good luck
