Used is great option.
'Nuther option, Academy Sports just opened around here. First week the 870 Express was $219, second week the 870 Express $199, this week $10 of any rifle, handgun or shotgun in stock.
Considerations: Even if you don't have an Academy, keep eyes and ears open. Other stores may offer specials because inventory is coming up, they may even honor competitor's ads for specials.
Remember too, some folks buy a gun and sell it after hunting season...or maybe they need to pay for plastic used last month.
So figure in shipping and all, see what is local, and if for say you spend $199 instead of $139, in 6 months you will forget about the extra $60 you spent.
