Not that weird considering Amazon prices fluctuate daily (even throughout the day e.g. higher prices during lunch hours). Newegg likely does this as well. Als

Not that weird considering Amazon prices fluctuate daily (even throughout the day e.g. higher prices during lunch hours). Newegg likely does this as well. Also note that his prices are listed per unit, and the products are not always sold "per [rpi] unit". For example, a 7 port USB hub powers 7 RPi units, so unit price = (item price) / 7.
