Us customs Seizing stuff....

M1K3

for starters i ordered this p90x workout program from a china seller on ioffer.com (similar to ebay..just haggling involved) which im sure many people have heard of. i received it and was legit with no problems and everything was great! Now i have quite a few overweight friends and talked about this to a lot of ppl. I managed to get 10 ppl to want there own as well. I bought them from the same seller at wholesale for 400 USD.(a good deal) as they were delivered they were in 1 box and once they got to US customs they sat for round 4-5 days...way to long. and i received a letter saying my items were seized for illegal importation. Needless to say i wasnt very happy. now i am not buying and selling these. they were paid for by each individual and for there sole use. they are not priated, or an illegal video thats not allowed in the U.S. I honestly have no idea how to go about this. From what ive gathered getting refunds through paypal from a china seller is not easy. and getting my items to me is not easy either. Now i am pretty positive since they are not fakes, and even if they were, that i can not be prosecuted, seeing as they were never actually my goods. I am eager for any advice on this situation...all i get from google is people who have imported pirated dvd's to resell. neither of which apply here. Thanks for any advice.
