See, good things come to those who wait, or should I say waited as these are sold out.
But for future reference shipping is 7 bucks for a bundle of ten, and 7 dollar shipping seems to be a standard for small things at PSA. Uppers might be more, but I buy Noveske and BCM so I couldn't tell you. Although if PSA ever gets back to its old sale pricing I might buy a few of their uppers and stripped lowers.
