We're okay with that, provided that you aren't doing it merely to knock shopping the big national or international chains. At the end of the day it's about shopping for what you want where you want. There are advantages both ways really.
Think what you want, there tend to be better buys for the common goods at larger stores and there isn't anything wrong with taking advantage of that. Smaller neighborhood stores are typically niche stores, and there are good things about that. If you want something quirky or unique you'll often find it at a place small enough to be quirky and unique. And if you think that's helping your friends and neighbors, well, you're right. You are.
Yet you're helping them too to shop the box stores. How many friends and neighbors work at them? If it's keeping the money local which worries you then it's at least worth considering that the wages they earn and the taxes they pay, much of it, anyway, stays local. Why be all hung up on money staying local as it is? Everything's local to someone. So WalMart's profits go to, where is it, Arkansas? Wherever their products are made is local to those folks, isn't it?
The bottom line is to shop where you want and don't try to shame others about where they spend their dimes. This means that the box stores mavens must reject their sneering about shopping local for those who want to while the supporters of the store next door end their holier than thou tactics as well. To us, that sounds like the perfect solution.
