Based on the provided sources, it is unclear whether there are any discounts for bulk Lipitor orders. However, it is possible for pharmaceutical companies to offer discounts to insurers and bulk purchasers.

The first source, Drug Patent Watch [1], provides information about the expiration of Lipitor's patent and the availability of generic versions of the drug. It does not mention any discounts for bulk orders.

The second source, PubChem [2], provides information about the chemical compound atorvastatin, which is the active ingredient in Lipitor. It does not provide any information about pricing or discounts.

The third source, Forbes [3], discusses the practice of pharmaceutical companies offering discounts to insurers and bulk purchasers. The article specifically mentions AstraZeneca offering discounts of up to 60% on the list price of its drug Nexium. However, there is no mention of Lipitor or its manufacturer, Pfizer, offering similar discounts.

In conclusion, while it is possible for pharmaceutical companies to offer discounts for bulk orders, the provided sources do not provide any information about discounts for Lipitor specifically. It may be worth contacting Pfizer directly or consulting with a healthcare provider or pharmacist for more information on pricing and discounts for Lipitor.
