First of all, it is a requirement generic Acyclovir to be tested and shown to be no different than the brand name Zovirax, including side affects, safety, and risks. These examinations are conducted under strict supervision using a step-by-step scientific methodology, initially in a science lab and then, before a drug is approved, at a clinical lab for a lengthy period of time.
While this is a drawn out process with many opportunities for part of the system to fail somewhere along the way, what is important to us here is that there is no research involved, which cuts the expense of developing generic Acyclovir by 60%, 70%, or even more. This is perhaps one of the biggest reasons they are called "cheap Acyclovir", but this is not the only reason.
Brand name Acyclovir that are protected by a patent have sole and monopolistic price regime for two decades, which is longer than most patients can afford on a continuous basis, even though insurance and social security systems make half-hearted attempts to help. In India and countries with similar economies, cheap Acyclovir are more than a million dollar business, Acyclovir made in such countries are cheap and are sold via online pharmacies.
What is the reason that generic Acyclovir are cheaper at Acyclovir online pharmacy than offline drugstores? You can purchase generic Acyclovir online anytime because everything, with the exception of dispensing them, is automatic, while the actual dispensing is completed far away, usually by manufacturers or stockists who are working in countries where generics manufacturers are located, removing any inventory purchasing and holding investments for online pharmacies. When you put in an order to buy Acyclovir online, your order is processed and shipped from the least expensive producer in the store's network of manufacturers.
This becomes a bonus for both Acyclovir online pharmacy and economical Acyclovir pills producers at the expense of offline pharmacies. Acyclovir drugstores operating with a physical address face disadvantages compared to those who primarily operate online, mainly due to drastic differences in business paradigms.
Speaking of paradigms, the offline physical pharmacies have additional disadvantages caused by the tax structure where they operate, which ironically erases all of the benefits the government and medical insurance would have otherwise provided.
My theory is that if all generic Zovirax produce similar results, why not save some money by ordering them online?
