Lots of info in that thread. Bottom line, don't do at base. Way too much work for $10, especially the larger stores who have multiple displays. Try out a small store first or go into a store and see what they have first. I have done this with a few of the larger stores.
Jobs are pretty easy but some of the displays are dirty or very messy and it takes time to sort and organize. Then there are stores that are so simple and quick because the stores keep the displays neat. Not hard work but be prepared to bend to get to that bottom shelf.
