He has a point,
PSA does do a little bait and swithc, BUT if you look closely, some of the prices doesn't change, despite the fact. For example, the Taurus PT-111 price stayed the same w/o shipping and w/free shipping. Or the American eagle 5.56 ammo, that price stayed the same with or without free shipping.
As the guy above said, you'll have to sift through the sea of bs, before you find the ham.
I lvoe PSA and as the guy way above said, careless for "savings" just focus on final price. Start memorizing price, emails and start logging. It paid of great deal for me....despite spending a boatload on PSA already.
