The products you buy are built and sold my a soulless, heartless, mindless corporation to a souless, heartless, mindless public.
This is one of the long term methods, describing sustainable ways of operating in an unbranded society. This is the stuff of pipe dreams, which hopefully, one day, should enough people buy into the dream, will come true.
On the other hand, it makes sense from an unbranding perspective not to do business with those corporations involved with branding, which means staying away from large companies for the most part. What's left over are small, local companies where you actually have some chance of having an impact on what's carried in the inventory.
This method may be at odds with Thinking Thifty, since a local store may be more expensive than the megamart down by the highway. It is important in these cases to consider the true cost of whatever it is you're buying.
Shop at local stores. Get to know the owners. Ask them for advice. Tell them what you like and dislike about their stores. Ask them carry products from other local vendors. Let them know you'ld rather have quality products than the branded crap you can get at the local megamart.
You wallet !
No special skills are needed. Being shy doesn't help here though.
You build up a feeling of community. Besides that, you are helping to build up a zone of unbranded stores in your loal area where you can go to get quality products from knowledgable vendors who have a real stake in making sure they keep you happy. Contrast this with being assaulted by mind numbing adverts from an inaccessable corporation who doesn't care what you want individually as long as a million or so of your neighbors don't mind buying whatever garbage is sold to them.
