Two locations near me. One chicken shop one gas station convenience store shop each have two of the same identical shops listed. I did the chicken shop on Monday. If I do the other chicken shop should I wait a week or so. Or not do it at all.

It's not uncommon for the same locations to have multiple shops posted, though there are usually some "rotation" rules in place - i.e. that the shops need to be at least X days apart, or that the same shopper can only do shops at the same location once every X days.

I'd check with the MSP if it would be okay to do the other shop again this soon - they'll let you know.

Ivan is correct, the MSP usually require no visits for X days regarding the shop or Y days between visits, however the system usually tracks that and won't let you select the second shop at that locaton based on its site id.

Rare but I have even seen shops at the same location for different MSP. Good thing that doesn't happen too often. The one I am thinking about is a variety store with a name brand gas station. Different shops and MSP for the variety store and gas station.
