Good they shouldn't take anything back, because they are greedy and it could cause the virus to spread more by that stuff coming back into the store
I think that's the main issue...and they may be pressured to do this policy by state health departments, etc. We want as few people touching merchandise as possible. It's already hard enough for me to remember to bring disinfectant wipes when I go to the store...I don't want to be picking up stuff that's been touched by 5 extra people and their kids...
