    Dangoodbuy started out entirely by accident, but absolutely out of necessity. Our former owner, Dan, was fed up with having to buy 1000 of a product he needed because nowhere sold the 12 units desired for his home project.

    With rubber grommets, rubber plugs, grommet bumpers, rubber feet, thumb screws, tack bumpers, and more, dangoodbuy is a DIYers dream as we have very small minimum order quantities (as low as 1), free shipping, and bulk purchasing available.

    And if you need a product that is unavailable, please reach out to us at dan@dangoodbuy.com and we'll try to help.
