What happened to SSA's 6.8 "plinkering" round?

What happened to SSA’s 6.8 “plinking” round?

Reportedly the 90g OTM round was going to be the sub $15 a box plinking round. BUT, for the last week they have listed their 90g TNT round as a “plinking” round and selling it for a small discount (regularly priced the same as the 110g pro hunters).

What gives? IS the TNT round the much anticipated low cost round, and if so why is it priced so high? IF it is not, why the confusing labeling on the web site:

It is not the plinking round. SSA is reportedly investing in some new machinery to be able to offer a lower cost practice load.
