A few months ago, we first reported that the price of the LEGO Collectible Minifigures will be increasing in 2020 and it looks like that has been confirmed by Brickseek. The LEGO DC Comics Collectible Minifigures (71026) are now out at Toys R Us in Canada as well as to a few RLFM sites and we can see the UPC number for the minifigures as 673419319362. Crosschecking that on Brickseek, it shows that the price has jumped to $4.97 which is Walmart pricing but it pretty much confirms that they will be $4.99 per pack.
Again, I’m not sure why the price has increased but note that for this wave, each minifigure will have a jumper plate along a trans-clear piece for action poses. I doubt those two additional pieces are the reason for the dollar increase but there could be other behind the scenes things that also factored into it.
