There is a cost reduction on Viagra if 30 to 180 pills are bought at one time. A person can save up to $390 if he buys 180 pills of Viagra instead of buying just 10.
Many pharmacies, including Walmart, offer heavy discounts on Viagra. Great discounts can also be found on Viagra when bought online. Also, generic Viagra (Sildenafil Citrate) is much cheaper than the brand name.
