I was joking with my son about making novelty stuffs like personalized t-shirts to give away free to my blog readers. We can insert funny messages inside and make each a unique one. Of course, I will also insert my URL in there.
Looking at the cost of per t-shirts, it is actually a very good idea for promotion and marketing. Of course, I am only joking about promoting my blog. But for those big companies, they should seriously get these good quality shirts for mere $2 per piece and get them stitched or embroidered.
Take a look, some of the white t-shirts there are really, really cheap.
