Where to find deal on Garage Door?

[yaui]

:o I have 2 wooden garage door and one of them cannot resist Canada's extrem temperture, the panel start peel off and I could not find the section or panel replacement. So I am looking for deals to replace 2 8' x 7' door. Checked HD and they ask for around 2000 for the value door installed.

Any suggestion where i may find a deal?
