I bought a Cody Rhodes tee from the online store using a discount code. Since it was under the customs limit I shouldn't have been charged, but I still was. Shipping price doesn't effect customs, and the discount came off the tshirt itself, so legally I shouldn't have been charged.
Got hit with £11.43 (around $17.75 for you Americans) customs charge. They said I either pay it or they destroy my products. I tried to see if they could return it and I could get a refund because that was more than the tshirt itself (not including postage) costed. I did some research and found out the company doing customs for WWE products was breaking the law. Kicked up a load of shit, contacted the actual UK government customs department, then contacted the people charging me more than my tshirts worth in customs with all these claims of them breaking the law and reporting them. Person in the call centre didn't know what hit them, so they put me through the manager who claimed I they were in the right, but "just this one time" they'd release my item to me free of charge. They just didn't want to lose face.
Tl;dr - Don't buy from WWEshop US if you don't want to deal with customs bullshit.
