Previd, I usually agree with you, but IMO you're out of line here. If TD's policy is that you can change your mind and refuse a deliver to return the item, then there's absolutely nothing wrong with doing so for any reason. This is not at all like taking delivery of the camera, shooting a wedding, and then returning it for a bogus reason.
In setting their policy, TD has factored it in as a cost of doing business, and adjusted their prices accordingly (if they are rational businessmen). It's an individual decision for the business - some don't charge anything, some charge a "restocking fee."
Returning something within the terms of sale is just not immoral in any way, IMO. And that's my two cents.
Oh, and OP, check out the HV20 price at Comp USA right now.
