Nah. Target Sports USA is more than a drop shipper. I finally ponied up for the $99 prime membership (standing discount, plus free shipping), but I and many others here have bought from 'em for years.
In normal times, they're among the best-supplied and fastest national ammo retailers around. They, in fact, were keeping up better than most in the first couple months of the 'rona scare ... just 2 to 3 business days delay from order date. (In non-panic buying days, they'd usually have your order out next business day).
They couldn't have done that if they were merely drop shippers.
