The most cost effective (and my favorite) way to purchase videos is through subscriptions. These sites sell individual videos but they also offer subscriptions. A subscription gives you unlimited access to download what you need, when you need it, for an entire year – for one fixed price. Subscription prices vary, but your money is well spent on these sites. Although some of these sites are expensive the amount and quality of product you get is usually worth it. Many of these companies will offer their subscription at a discounted price two or three times a year. Subscribe to their newsletter and follow them on facebook and twitter to get the latest updates, free videos, and discounts.
