they get ya with some shipping costs.... for 2 sets (enough for 4 mice) total cost me $12.63.

Like $8.63 shipping. They COULD ship em for $2 if they tried harder, but they don't. It came in a plain brown 11x17 padded envolope with 3 sheets of paper. 2 stripps stapled to 2 sheets each and a Packing Slip.
