There are many ways to find the best deals when shopping for building materials, and this can make a huge difference in the cost of any project. One obvious way is to look for used or recycled materials, and this can be done through local want ads or going to stores that sell deconstructed materials.
If you are looking for new materials, a few phone calls to local stores can often result in significant savings. You can ask building suppliers to give you a quote for a package deal, and this frequently produces savings.
Another approach is to do some shopping online, at least to compare prices. Sometimes the larger suppliers have an online store where you can order products that are then shipped to your local store. There are some internet sites where you can compare lots of of product sources for prices and availability.
