New place halfway between Bancroft and Minden so Wilberforce was worth trying out. The Tim-Br Mart had everything I needed in the way of wood and hardware (some I was reusing so the hardware part was pretty easy). The location was very convenient and the guys were great.
Not sure about summer pricing with cottagers, there seems to be a premium to be paid around here. If your building project is substantial you might want to price in Barrie or Peterborough and then negotiate locally.
