Because Tengaged only has around 5 dedicated shop owners, each of which has accumulated a large amount of T$, anyone posting for less than 1000T$ on a competing week with more than 3 shops competing is bound to fail. Even if the shop owner does better by the Tengaged public and gets more sales, the shop owners will just buy out their own stock anyway and move on because their shop will be worth more T$ than the shop with lower selling designs.
It is now impossible for anyone to post below 1000T$ and have any chance of moving on because of this.
