If you stock it from the front, then there could be a couple gallons in the back that never get bought. Unless they let the stock run out completely before restocking. Plus with thing like milk, it is a real pain to push several gallons uphill to put something else in front (ever try to put a milk container back on the sloped shelf? Takes a couple hands and some fidgeting to do it).
