Aestivation or æstivation (from Latin: aestas, summer, but also spelled estivation in American English) is a state of animal dormancy, similar to hibernation, characterized by inactivity and a lowered metabolic rate, that is entered in response to high temperatures and arid conditions. It takes place during times of heat and dryness, the hot dry season, which are often the summer months.
Invertebrate and vertebrate animals are known to enter this state to avoid damage from high temperatures and the risk of desiccation. Both terrestrial and aquatic animals undergo aestivation.
Organisms who aestivate appear to be in a fairly "light" state of dormancy, as their physiological state can be rapidly reversed, and the organism can quickly return to a normal state. A study done on Otala lactea, a snail native to parts of Europe and Northern Africa, shows that they can wake from their dormant state within ten minutes of being introduced to a wetter environment. Fossil records show that the act of aestivating may be several hundred million years old.
DirectBuy is a membership buying service headquartered in Merrillville, Indiana. It claims that it is the largest franchiser of members-only consumer buying centers in North America. Members pay a significant fee, which then entitles them to buy merchandise "directly from the manufacturer and its authorized suppliers".
Product categories include home furnishings, home improvement, entertainment & outdoor, flooring, and accessories.
DirectBuy was founded in 1971 in Merrillville, Indiana by James L. Gagan, and the first Canadian franchise was founded in 1996. The company was incorporated as DirectBuy in 2004. United Consumers Club (UCC) remained the holding company for DirectBuy until December 19, 2007, when DirectBuy was acquired by Trivest, a private equity firm, and Allied Capital Corporation (stock symbol: ALD) with $83 million to support the buyout.
Initial membership costs vary by franchise location and have two or three year terms. In 2007, Consumer Reports reported that memberships at some DirectBuy locations in the New York area ranged from $4,600 to $4,990 for a three-year membership and then $190 a year for the next seven years. In 2009, the Star Tribune reported that enrollment fees are $4,700 and then $99 a year after 30 months. The customer must decide at the time of their Open House visit, before leaving the showroom, whether to join DirectBuy after receiving a presentation of services. DirectBuy states that a customer may be shown confidential pricing during the Open House, and its "policy is in place out of respect for our members, manufacturers and the retail industry. It also prevents consumers from asking traditional retailers to match DirectBuy prices." Some franchises are offering 30 day trials to certain potential clients, valid for up to $1,000 in purchases.
