I bought around 800k bells' worth this morning, at 91 bells per. Last week I bought 5000 turnips, and sold them for almost 1.5 million profit. (which was rounded down to a million because I paid off my house at the same time.)
I think that I had more than 4 lockers worth of 100 turnips packs, in which I had no choice but to lay many many of them down on the ground.
I can tell that selling all of them takes a long while, but not as bad as I did in ACCF. Oh boy, I sold like 1675 packs of 100 turnips, and ended up reaping 89+ millions of bells. It took me 3 hours to fill my town with turnips, and another 3-4 hours to sell the majority of the turnips!!
Most I bought was 205 bundles of 100 for a total of 20,500 turnips. Ended up selling them at 614 and I made over 10 million in profit. Hoping for an even bigger profit this week, especially since the price for turnips was at an all time low of 93/turnip.
