No offense (and sorry for being off-topic) but I never get how people obsess over the under 1 or 2% cost savings while completely ignoring the overvalued principal. Two other examples,
- People go over to buy a $50-$70k car and later boast how "they made" the salesman give them a $500 or $1k discount. (well what about a fully-functioning $20k car, or the same car but 2-3 years old but costing $8-12k?)
- People buying stupid stuff off amazon etc, and worse, travelling to random places, just because they have credit-card cashback and travel rewards, and looking at you funny when you tell them you only have one credit-card and you make sure you don't overspend but never paid attention to how many points you accumulate.
