How do you get your shipping operations tightened up before the holidays? We at InfoPlus recommend that you have at least two carrier services enabled (even if you plan to ship with only one service). That way, in case of service interruptions on those busy days, you don’t have orders sitting around waiting to go out the door.
For example, if you always ship FedEx, just get UPS set up as a backup - if you don’t end up using it, that’s okay too!
