And the climate adds its own wrinkle: sun exposure degrades roofing and paint faster than in overcast climates, shortening replacement cycles by 20-30%.
What Matters Most

Pro Tip
Store-brand items at Costco, Aldi, and Trader Joe's are often produced in the same factories as name brands. A family of four can save $200-400/month by switching 80% of purchases to store brands.
Common Mistake

Best Time to Buy
Grocery prices spike around Thanksgiving and the Super Bowl. Stocking up on staples in October and January avoids the seasonal markup.
