We went into the Direct Buy presentation expecting the worst. However we were treated with respect and never pressured. We purchased kitchen cabinets from Direct Buy.....we saved over $10,000 on this large purchase alone. We had priced the same cabinets at a local cabinet "wholesaler" and knew what our local best price was. The design service provided by Direct Buy was quite helpful...all cabinets arrived within the promised date range.
The down side of buying from direct buy is the waiting period required after ordering your merchandise.
I know I have recouped my initial investment from Direct Buy and then some.
If you do not plan on a major project the savings from direct buy will probably not offset the membership.
