@cliffside I’ve found a few dealers that sell full sheets for 20-30% off face value at stamp shows. It really depends. But yes you most certainly can find them for cheaper than face value.

I’ve sent you a message but wanted to add this link as well. You are looking for .30 cents and above stamps this is a good deal I tried to count the value and i think it’s around $110-$120 worth
