Grace shifted all the stock from the Retail store inside her space. Initially, she didn't plan to stock up too much water supplies since she had unlimited water available in her space. But since she came across the store during their hunt for supplies, she decided to just get the products since they were available right in front of her.
Not putting special efforts in locating these supplies was a different thing, but ignoring them when they were this easily available to her - it would have been a completely stupid decision.
