I just hope B&M stores will offer competitive prices with Amazon, now. Even with sales tax, most electronics I buy are still significantly cheaper than my local Best Buy before tax. For instance, I found a Plantronics bluetooth earpiece I liked at Best Buy for $50. Then I checked on Amazon and it was ~$25. If it was only a couple dollars difference, Best Buy would've gotten my business, but not when I can get the same thing for half off. I even told them I would pay 10% more than the Amazon price at Best Buy and they declined. So, until the B&M stores learn to keep prices somewhat inline with what I can get the same item for online, I won't be shopping there.
Keep in mind (and this isn't necessarily directed at you - but it does open the door to the discussion).
A B&M store is also paying property taxes that supports the schools, water, sewer, police, fire, roads, etc in your neighbourhood (or in a nearby one). On-line retailers don't. Usually they locate their warehouse in locations with minimal property taxes, plus warehouses are taxed at a much lower rate than a retail operation. This property tax is an expense that gets passed on, but it also subsidizes the property taxes that you or your landlord pays. Usually, commercial property taxes are higher than residential.
A B&M store is also paying to maintain a bunch of parking spots, either directly if they own the property, or through their lease. On-line retailers don't.
A B&M often has a budget for supporting local charities or local events (sponsoring a sports team, or donating surplus goods to a school or club). On-line retailers don't.
And of course there are the jobs that a B&M store brings to a community. Those wages circulate through the community, and are somehow benefiting you in lower taxes, lower fees, something somewhere.
A large portion of the "extra" money you pay a B&M store stays in your community. And an on-line retailer doesn't.

One of the things that never fails to amuse me is listening to someone complain that their community is dying a slow death, with stores closing everywhere.... while buying their stuff on-line.
