This has been my experience:
Dillards (GEMB) pulled TU, reports to all three CRAs.
Hooters (Merrick) pulled TU, reports to all three CRAs.
Target pulled EQ, reports to all three CRAs.
Walmart (not sure who they pull from, but they're GEMB so probably TU), reports to EQ and EX.
Also, Fingerhut reports only to EQ. Don't know who they pull...
