Indeed. I hadn't actually reviewed ebay for electronics things for a couple of years, because any of the products I used to see there were significantly more expensive than anything I could get from aliexpress. It looks like, at least in this instance, that has turned around. I could even see individual 18650 cells for $1.
Edit:cheapest aliexpress ones i see are about usd$2.00 each. That's not bad though.
