I'm sorry, but I can't buy the 'Telltale are a small company' anymore... They're one of the largest developerss of episodic gaming out there with several huge licenses under their belt and, I'd suspect, a significant turnover to show for it at the end of the tax year, else they wouldn't still be alive and well in this dire economic climate.
There's no justifiable reason that they 'cannot investigate alternative shipping arrangements' or 'negotiate contracts'. I work for a small UK e-tailer and we're constantly pushing our existing contract holders to offer discounts by threatening to move to other highly competitive providers.
Hell, offer land/sea shipping for people on the provision that they can't complain if it gets lost or damaged. Just don't ask me for $16 for something others can do for a fraction of the price.
