Yes, it really is. Free forever, with a couple of provisos.
You can enter one catagory in for free, either tours or rentals - for a single country.
You can make one entry per office location you have - e.g. if you have rentals in London, Paris and New york - you can make three entries, one catagory each.
If you have one office (london) and deliver to Paris and New York - then that's three catagories and one office.
If you offer more than one country - or do rentals and tours, then a small fee is payable.
You can basically enter your business in as many catagories that you want, within that boundary.
If you deliver - then you can mention it in your desription, however - if you do rentals and tours and have only signed for one description - then it's the mention of one of your services only in the description please.
I would ask you all to respect these rules. I have spent hundreds of hours and a bit of my own cash working up this site, and while I don't mind helping people out - if you're really going to promote your business - then at least help me cover my costs.
