Corey, they are a wholesale company. You should have a wholesale license to buy from them, but I know they have allowed a couple of people to buy in quantities without a license. You do need to buy a bag or box of the bulbs, so at least 25 of one bulb.
But buying wholesale comes with clauses. You normally only have 48 hous to file a complaint if your items are not what you expected, and you can't complain later on if they are not true to name, or don't come up in the spring. Some companies that sell wholesale to the general public stop soon after they start having to deal with a non nursery person that's mad that the hyacinth is yellow instead of white. I don't think wholesale companies should sell to the public. But having said that, I love ADR.
