$3.98, wow, I was thinking it was more like $6 or $7 or in there somewhere.
Of course you have to remember that $4 would have bought you between 12 and 16 gallons of gas in those days. What does 16 gallons of gas cost you today?
I remember the 1/32 Phantom Mustang was priced at an astronomical $4.99. By comparison, the Revell 1/72 B-17 and B-24, when they appeared several years later, were $1.99.
