You can get a 91/30 on the internet for 90$, but after shipping,
FFL, and taxes and fees, you may find yourself saddled with a
mismatched, re-arsenaled POS.
You have a much better chance of getting a rifle with
matched serials and a nice stock if you can look at it before you buy.
Shipping will be part of the LGS's overall higher price, then.
Some mail order places let you specify a "hand selected" rifle
for an additional fee, which IMHO, is well worth it, especially if
they will guarantee a hex receiver and matching serial #s.
Bear in mind you will have a long time to regret not spending
enough, if you wind up with a less than satisfactory unit.
