Getting one of those done in under half an hour would be amazing. Just consider if you are pricing Tylenol caplets, regular strength, 100 count, 500 mg. There are literally dozens of types of Tylenol in caplets, capsules, gel caps, dissolve packs, extra strength, migraine strength, arthritis pain, 325 mg, baby size, 24 count, 30 count, 50 count....well you get the idea. Just making sure you are pricing the right item would be time consuming. And that doesn't take into consideration the time it takes to move from area to area within the store. I did a big pricing project similar to this a few times. It was 300 items and took me about 12 hours. That was in a store I did my personal grocery shopping at all the time, so I knew where everything was.
