Because when you do business, you have a certain expectation of service without constantly have to follow-up. In 3 months of dealing with firearms businesses, I have been less than impressed, pledge not fulfilled, delays, lost shipment, mistake from the shipper. In all my years of online shopping, this is probably the worst I have seen.
My track record currently is: 1 outstanding (for a firearm), 1 average, 2 below average, 1 real bad (no firearm involved)... Maybe I should lessen my expectation of service, but there is still outstanding companies out there, so I won't.
