Well, I don't even know if the Muscle Machines would sell in PA, but I kinda didn't want to break up the set. It was hard putting this one together since most of the Dollar Tree stores in my area sold out. Easter baskets, lucky kids.
But,,,if Dean only has 7 of the cars you need, it may be the only way to help you out. Unless someone else can come up with the others that you need.
I have an extra red Vette (bought a bunch of those to paint) And I saw a bunch of the gold Thunderbolts at the one Dollar Tree that still has them, but the others are gone.

And I managed to find the first three 5 packs. No idea if the others will show up at all, ya know?
