Ive always thought of it as really limiting where you buy geographically. It is like getting a delay... say you bought at a gun show or are traveling on the other side of the state but get delayed, or now have to wait these 3 additional days. you may not still be in that area in 3 days, or the shop at a gun show near you may be located on the complete other end of the state. it is a logistical pain in the ass, and they're doing it on purpose. by a thousand cuts...
think of all the additional greenhouse gases that will be created from having to go back and fourth to shops by the fossil fuel driving gun crowd all these additional times,...the horror/ sarc.
