From Ammoland:

UPS has stepped up its anti-gun campaign by requiring online sellers to ship an average of 50 handguns daily to use its 2nd Day Air service.

Sellers who do not ship at least 350 handguns a week risk losing their shipping accounts. Under the new agreement, UPS is only required to give customers a ten-day notice before cutting them off from the shipping service. The volume necessary means that most online retailers and manufacturers are now cut off from shipping guns through the carrier unless the handgun is shipped using the expensive Next Day Air service.
