There’s almost 500 action figures on sale during TFAW’s Gray Days of November Sale, which is on right now. I’ve found prices there start a bit high to begin with, so it takes some exceptional discounts to make it a good deal. So you may not find the prices that you’re looking for in their Hasbro (with Star Wars and G.I. JOEs as the bulk of the items) or Mattel DC sections, but look through and you will come across some gems.
For example, the excellent Ultraman, Power Ring, and Superwoman Crime Syndicate figures from DC Collectibles are under $13 each, and the Danaerys and Ned Stark Game of Thrones figures from Funko are under $14 each. I just did a quick run through, so there’s probably more deals worth pursuing that I missed. Happy shopping!
