I look all the time, make a list of what you need and the card number.
Thats makes the search easy, as you can always see that number and can skim through racks fast.
I collect the 70 Buick GSX
card number 07/42
Got plenty of yellow and white, could use a few more red's and any of the new wild color's.
But I would take any color in the short card, see below.
only have 1 in red. like to have 10+ of each color n card style.
