One of the interesting elements of the A0K1Credits contract is the implementation of the presale. The presale price is the same as the regular sale price.

function activate(
    uint256 startTime_,
    uint256 duration,
    uint256 presaleInterval_,
    uint256 claimStartTime_,
    uint256 claimEndTime_
) external override adminRequired {
    _activate(
        startTime_,
        duration,
        presaleInterval_,
        claimStartTime_,
        claimEndTime_
    );
}

Following the inheritance structure, this activate method calls the _activate method in the CollectionBase Contract:

function _activate(
    uint256 startTime_,
    uint256 duration,
    uint256 presaleInterval_,
    uint256 claimStartTime_,
    uint256 claimEndTime_
) internal virtual {
    require(!active, "Already active");
    require(startTime_ > block.timestamp, "Cannot activate in the past");
    require(
        presaleInterval_ < duration,
        "Presale Interval cannot be longer than the sale"
    );
    require(
        claimStartTime_ <= claimEndTime_ && claimEndTime_ <= startTime_,
        "Invalid claim times"
    );
    startTime = startTime_;
    endTime = startTime + duration;
    presaleInterval = presaleInterval_;
    claimStartTime = claimStartTime_;
    claimEndTime = claimEndTime_;
    active = true;

    emit CollectionActivated(
        startTime,
        endTime,
        presaleInterval,
        claimStartTime,
        claimEndTime
    );
}
