There was a very serious bug in the Bazaars, ( See Bazaar Repricing Bug thread) every time an item was priced or repriced =>$1T in the bazaar, the bazaar item's number replaced the actual items price (eg Bazaar Item Number 127=$127 price/item instead of the actual input item price >=$1T). Recommendation was to set a item price limit of =$1T per item, as pricing could be set up to $1e27 with the resulting pricing error.
4000 + items in my bazaar were actually repriced and sold in the Bazaar at $127=Bazaar Item #127, before manually fixing items prices, these items were not sold at the actual price of $1T but $127 each, an obvious error. To date all but 2,966 items returned but by one buyer.
The recommendation was to set the maximum price at =$1T per bazaar item, not $10B, see details in Bug history for details.
