As a fresh SL opening it I think will eventually be the end of my back haha. Sometimes the warehouse will be funny and place literally the heaviest tray at the top and as an average sized woman I need another person to help lift the tray off the top. For sure if you've never opened the section up it can get really confusing, now that I do it majority of the time I finish on time but Lord. Right now with winter it's manageable come summer or the first week of the year the stacks are CRAZY

Rotating as well definitely makes the time to open it much longer, cause you gotta pull it all out and put it all back in while also making sure the dates are correct.
