It was a 24hr sale, sorry I should've made a post here, I was just too busy. Other ML that were on sale was the Cap/Peggy Carter two pack for $35, Deadpool w/scooter was $25 (Still is, I'm tempted to order that one too) X-Force Wolvie, Cannonball, Boom-Boom, and Weapon X were $11, Dora Milaje was $10. Some are close to that discount at the moment. I checked others I've been waiting to go on sale (Juggy/Colossus, Wolvie/Hulk, AIM soldiers, Arnim Zola/Hydra Cap two packs) None were on sale at the time.
I'm almost certain another sale will pop up on Amazon. Add the figures you want to your cart and save them for later, when they discount you should see the change in your cart, that's how I found out about the sale.
As for cutting the plastic on Retro Grey Hulk.... yeah wait until you get yours. It's bigger and more substantial than regular Retro cards, looks great and not something I want to cut, unless yours arrives damaged. Mine arrived pristine from BB so hopefully you should be good.
I plan on getting the Wolvie/Hulk two pack one day and that will be an opener.
