I don't think it's necessary to flood TSUSA with orders right now in order to show your appreciation. What's important is what MA consumers do to show our love three, six, and nine months down the road. I'll probably set up my account over the holidays and start ording sometime in late winter. I don't buy much ammo, but it's worth nothing that they sell components and lots of other firearms related stuff.
I also think that, even in a Massachusetts court, the AG's position vis-a-vis out of state vendors is dramatically weakened once the vendor takes reasonable measures to ensure that their customer is legally permitted to possess ammunition. The law is poorly written and there is no way that an out of state vendor can get a Massachusetts license. It's just not avaible and they don't sell IN Massachusetts. BTW, as written, the law prevents Massachusetts businesses with an ammo sales license to operate an on-line commerce enterprise and sell to people in other states. MA is effectively regulating interstate commerce.
There's practically zero chance that the AG or anyone else will target consumers over this. The AG's teeth come via chap 93A, consumer protection, not chap 140. i.e. it is an 'unfair and deceptive' business practice to sell ammunition to MA residents. Just like with the AG's handgun regs and the AWB, it's all about intimidating businesses into abstaining from the conduct that the AG thinks shouldn't be permitted. That simply doesn't translate to consumers. That's also the reason I don't think that individuals are going to be prosecuted based upon the the AG's 7/20 enforcement notice, even if they acquire or transfer so-called AWs after that date.
