The Deluxe Beverage Package states buy 2 get 50% off. This is on their website. I bought 3, but did not get 50% off the 2nd package. They say the discount is 25% off each package. Since I purchased 3 We notice they are all the same price. We did not receive any benefit by purchasing the 2nd. The two individual packages are the same cost as the 3rd package. We brought this up to Customer Service, they will not budge We cannot tell if they understand our position . Their position never changes and they keep repeating they are all 25% off. Why advertise something that is not true? We feel it is false advertising. It doesn't matter if you buy one or 5, they are all the same individual price. No price break for purchasing 2. Anyone have a similar issue? Thank you
