Roger's still has some great deals, and is one of the simplest to deal with under the current regs. All you need is an FFL on this end who is willing to receive the shipment and do the FTF transfer. No paperwork required for the transfer (this year), but the FFLs are supposed to collect sales tax on the price of the ammo they transfer to you, so the deals are not as good as they used to be.
What we have really lost (other than a big chunk of our 2A rights) is the ability to order small lots of odd ammo that you can't find locally. One FFL told me he won't do transfers, but he can order whatever I want. I didn't argue with him, but he simply cannot get the oddball stuff that I sometimes shoot, because some is discontinued and only available from private parties.
