Gamestop has a lot of their clearance action figures for $5. There isn't any in stock online, but you can check to see what to look for if you go to stores. Some of the stores I went to didn't even have everything marked down properly but they still scanned $5. Some stores were already picked over (I went to 11 in the area because I'm a sucker for cheap stuff, but only had luck at 4). I hadn't intended on building a Kree Sentry but not I might build two. Also includes Black Series, and other stuff, like Fortnite figures, and any DC Signature Series stuff they might still have from Mattycollector (and MOTUC). $5 for DCIE Ice? Sure why not.
15 figures for $75 and tax ain't bad at all. And my son got a 3.75 Fortnite figure, one of those mini figure four packs, and a weapons Llama. Best part, my 8 year old son went with me on the three hour drive around Western NY.
Good hunting.
