I agree that battle has largely already been lost, I was just making the point that this ruling isn't going to significantly help brick-and-mortar retailers as they are in competition with large online retailers who are already undercutting the local B&M shops by far more then the sales tax rates and won't have issues staying in compliance with lots of complex laws. I only see this negatively effecting small online business, the niche stories, single-person operations, etc. I'm not familiar with B&H specifically, so I couldn't comment on them specifically.

In photography equipment the local sellers are actually often very competitive if you set aside sales tax. If B&H starts charging sales tax I'll definitely go more to local seller.
