Yes, you are correct. People who are serious and sure about their project, plan to build classifieds website as lifetime business usually purchase forever plan. People who want to experiment with their project and to see what happens in a year usually purchase 1 year plan.
Thanks for clearing that up, I understand what you`re saying and would presume that in a years time after purchase, that if said business is doing well then purchasing the lifetime package would thus continue updates, support and so on.
Costing more in the long run but ideal if unsure how things may go regarding the script and their business.
