Are there any coupons for registering an account with MyUS?

Gonna be honest, I'm one of those people who will create new accounts with different services just to make use of their free trials and registration coupons. Used almost every streaming service at least once, it's a great way to save money. Anyway, now I need to ship some products from California to London and need the cheapest way to do so. Does MyUS have a registration bonus, like a coupon, that I can use to do so in the most cost effective way?
