I misremembered, it was $5 for 16GB DDR4 (not DDR3) sticks that I was paying on eBay. That might change the pricing.

Here's one I found in my email:

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.
