That's a great price for either, especially for DDR4. Only one stick though, right?

Yeah, I only bought single sticks at a time as I saw good deals on them. I only needed six sticks for three laptops. Just stuck a bunch of low bids and grabbed whatever I could. At the time there were tons going for $5-10 every day. Trying to stick to ones with free postage otherwise the postage would cost as much as the RAM back then.
