Regarding mugs, I have 3 Contemporary mugs, if I understand correctly, we cannot use them at VWL, do they take them back with some sort of credit and give you VWL mugs?? This may sound cheap, but if I remember correctly these mugs were about 10.00 or 11.00 bucks, I would think a trade in thing would be pretty good, they are getting some money back, and the soda costs almost nothing? Just curious.
