The appellant seeks reversal of his convictions on two counts of robbery with a firearm. We find no merit in the four issues he raises except with respect to a $2 cost assessment pursuant to section 943.25(13), Florida Statutes (1995). Because that cost is a discretionary cost and was not announced at sentencing, it was improperly assessed. Therefore, we strike the $2 cost item. In all other respects, we affirm.
