You do have a right to go after Commandermuon Grocery for abusing your trademark.
Usually liability traverses the chain of custody. If I give you a bag of chips, that doesn't absolve Frito-Lay of liability for a salmonella contamination issue associated with that lot of chips. Likewise, if I crush the chips and sell the bag to you, it's not Frito-Lay's problem, it's mine.
This stuff has been litigated extensively. There was a few cases around fancy grey-market watches that Costco was buying overseas and selling here at a discount. Costco provided a third party warranty to address that issue, but was allowed to continue. First sale doctrine applies here too.
Another real-world example is "grey market" cameras.
It is very common for camera stores to import cameras from overseas mass retailers in southeast Asia (IIRC Taiwan is a major source) and sell them in the US at a discount. The only limit is that the official Canon/Nikon repair centers know what region a camera was sold in and won't repair a foreign camera without a damned good reason (or a pro photographer rating, which entails owning a certain number of high-end lenses and so on)
Interestingly, in Taiwan it is common for camera stores to source cameras from Japan, alongside the official imported version. and the buyers can trade official warranty for a discount.
