Instead, you might feel like you just took a step back in time to March 2020. There currently appears to be a shortage of one of the most essential household items on every grocery shopping list. Yes, we're talking about toilet paper! Recently, Costco members have taken to social media to voice their frustrations about dwindling supplies of toilet paper on warehouse shelves .
