I used to be able to make returns from Marshalls at TJMaxx.....understand it is now against policy even tho they are both owned by same company ?

I used to work for tjmaxx and that was not possible at all but, when you return something and get a card with store credit you can shop at both stores with at credit

Return to same store!

Yes

You can return things purchased at Marshall only at Marshall locations.

Yes, that is the way I always remembered for the return policy. You can use the store cards at either but can not return Marshalls at TJ
