From an authenticity standpoint, they've seemed mostly fine. From a price standpoint, maybe not so much. This seller seems to get their items from a number of sources, so you may want to ask about items on an individual basis if concerned.
He is a big time chaser for in person successes in the Boston and surrounding areas, for a number of years now. Very good at hitting all the right places to get people about town himself (I've sure may have help occasionally) but he's good at. Stuff is legit. You can also see a lot of his successes on his fb page under the same name, everything for sale there too, I believe.
Thanks! Much appreciated.
they're good. i've purchased several aerosmith items from them.
