Shipping has went up for everyone, Canada and overseas, I ship mainly usps and they have changed the way you ship online now so they make more money. Global priority used to be the best route for smaller parts but they did away with it online.
I've been shipping from my home for over a year now and just recently can now ship everywhere in the world from home. Get yourself a scale, order free box's, print your own lables and/or customs forms and schedual a free pickup at your door.
I don't offer shipping outside the US on ebay only because I can't put a determined amount on shipping until after the sale so when asked if I will ship I always say yes but wait for the invoice before they pay so I can give actual shipping charges.
