If the supply is low or seemingly low on a specific part and the demand is high, the part could increase in value. You'd be a fool to sell it for less than what you could. I always thought it was the American way.
I hope LATOILETTE get the $90 shipped for the brackets. From courtesy they're: $41.98 $42.58 $12.91 $12.91 LIST PRICE = 110.38 + s/h Looks like he priced them and he's asking less than the list price.
