The one-cent coupon I grabbed in seconds suddenly showed expired. When I clicked on the page, it was still valid for one month, but the coupon code had been included in the expired coupons. I was so shocked. Fortunately, after communicating with the online customer service, they said it was okay and I could still use it. The key point was that the coupon number was crossed out. I took a photo and went to redeem it. The clerk was quite easy to talk to. He said it could be verified, and then I verified it. I ordered lobster balls, uh, there was no salad dressing, which was unpleasant, but it was sweet and flavorful. I like their balls, but salad and meat floss are still the most delicious.
