Yes... I suppose I DO need to factor in the cost of leftover materials... I was just excited that we didnt have to spend any money. Although the nails pulled from the porch WERE free since we did not build that porch, haha.

Yes, like I told someone else, if you want pallets, most likely you can find free ones. You can make an ad offering to haul them away, or just ask. Many stores have stacks of pallets out back that are doing nothing. There are tons of things you can do with pallet wood!
