Before sports card related blogging exploded in the last couple of years, Bob Brill, owner of KC Kings, published a weekly newsletter called the Brill Report. One of his most popular pieces was called the $10k Experiment. This experiment involved taking $10 and tracking the amount of time it took to turn it into $10,000. Mr Brill was able to accomplish this through buying and selling, including using his store as a means of low-balling walk in traffic for items people were looking to sell.
Today I came across an article he authored last month titled, "The death of the successful card shop, it's over."
Read it and come back and share your thoughts.
