Query: Nixon Politically Incorrect Adult Halloween Mask

I purchased this product on line 3 weeks before Halloween and it never showed up. The charges were processed on my credit card and one day before Halloween still I had no mask. Halloween came and went but still no mask was ever delivered. I tried contacting the seller and post office, but had no luck. Finally I contacted Amazon to get a refund for my purchase. This year I had no Halloween costume!
