AmericaRX.com shipping charge PER Item Internet

Buyer beware! I ordered through Amazon. I order a lot through Amazon and this the first time I feel I have been ripped off. Americarx is a third party. I really didn't notice that when I placed my order. I have been stockpile on things that I feel will go up in the near future, so I ordered 15 Dawn dish soaps at $1.87 each. Without realizing the shipping cost, $67.00 was taking from my account for this order. They charged me over $4.00 for shipping per bottle instead of on flat rate for all 15. I needed up paying way more if I would have gone to Target or Walmart. I thought when I was first ordering, I was getting a good deal. I am very upset, and will never order from this company again. I contacted them, and was informed it was their policy to charge shipping per item. Amazon should warn people of this rip off. I will no longer trust Amazon and will soon no longer order from them. I have over $400.00 of items that still need to be shipped to me from Amazon and after that, I will disable my account. That is how upset I am. Its a shame people are getting ripped off like this. Please take notice of third parties when ordering from Amazon.
