Speaking of, a local Oriental store gives me a free bottle of oyster sauce when I buy $100 worth of groceries. I collected 5 bottles of oyster sauce before even finishing the first one and I tried offering them to my grandma but she said she had like ten bottles of oyster sauce too. The next time I went there I asked the clerk if they had anything other than oyster sauce, and they said "nope" and put another bottle of oyster sauce in my bag.
