You won't even find another store that specializes in ham gear anywhere else in MA (or probably New England).
From what I've seen over the past year since I got my license, prices seem to be "controlled" so that they are all selling the same item for the same price. Occaasionally one will break away and you'll save a few bucks, but even that is rare. HRO ships almost everything with free shipping if >$100 order (some huge antennas they do charge shipping). HRO will also be at Boxboro
Home | Boxboro - ARRL New England Convention in September . . . if you order there for shipping from the store you'll avoid the sales tax. HRO will also be at Near Fest
NEAR-Fest – New England Amateur Radio Festival in October.
I get Emails from DX Engineering,
www.randl.com, GigaParts, BridgeCom Systems, Main Trading Company . . . ironically HRO doesn't seem to send Emails on what's on sale (almost all sales involve mfr rebates). On the same item, prices are almost always within pennies of each other. Some charge shipping however.
