The form, of course, has some mandatory boxes for you to fill in, including name and address, telephone and email address. One form I came across provided a box you could check to “reserve my Discovery Package.” It could have read “send us your blank check” since at this point you still don’t know what you will discover when they finally give you a price for the package.
Insulting folks you want to be your customers is not a winning strategy. Those of us who use the Internet to gather information and search for deals, which is all of us, know that once we give up our email address and phone number, we can expect a steady stream of contact from the communities in question that snag it. They all claim in their privacy policies posted at their web sites that will not sell our information to others, but there are conditions attached (e.g. insolvency or a “change of control”) in which your email address and phone number could be made available to others.
If you are interested in particular golf communities’ discovery packages but they don’t publish a price, my advice is to call them and ask for the price. If they insist on having your contact information before they will respond, look for another community to visit. In this market, you call the shots, not the developer.
