Great tip about buying your own shirts. Before a shirt is purchased it has no BSR score so by purchasing your own shirt your not only guranteeing it won't be removed after 90 days of no sales, your also giving it a BSR score and a kickstart in search.

I obviously don't buy all my shirts but when I have a design I really like and if I like the shirt or have a family member or friend into the niche the shirt is about ie bulldogs, knitting, soccer whatever I'll buy a shirt for them.
