1) As I've said before, I think we should have a regulation that states that any advertised price must include a way to get that product at that price. For example, "FREE* ...*+S/H"? If it's free, they should be required to offer ti to me free of charge (including S/H) as long as I am willing to inconvenience myself and go to their warehouse/location to pick it up.

2) This mouseprint is apparently even worse because you get something at a specific price but the seller is under no obligation to reveal the costs because they are simply acting as a middle-man of sorts to let you but a product from someone else. This sounds almost as bad as the rebate problem where you claim your product rebate from a different organization (which seems to benefit if they deny your claim.)

So YIKES! More deception in actual prices to worry about. once you buy the voucher, I assume you can't get your money back when you find out the real price (including handling/shipping/etc.).
