Perhaps you can anonymously call a Best Buy store, for example, and ask what downstocking is?
Hi, it's nice when shops go well, but for me I think a shop could be challenging if not followed and completed exactly as indicated for the shop to be. So if you do a shop and forget or do in error even one single thing that may seem small or like nothing at the time, could have a big impact: resulting in all of the valuable time spent on the shop being gone, possible money to get to and from the shop being gone, and or further money incurred to complete the shop being gone, and additionally...the fact of the history for rapport on the site. For this reason I try to follow instructions and do the jobs just like any other job (example: a server at a restaurant) because just like with other jobs, it could take only one mistake and a person could be fired permanently from the job and have that on file, with the staff and company involved knowing their name (who they are) and aware of the situation. But I think if there are negative feelings, that it's good to remember that you can simply not take on a shop or take a break from shops because as far as I know members are free to do what they want. However, if there is illegal or wrongful activity of another person or people/company it may be best to use conflict resolution skills and do so in a careful step by step way until resolution has been made, as well as keep a note or file about it for your own records because if someone accuses someone else of fraudulent activity (fraud) is serious.
