A lot of companies offer free items or discounts to attract customers but they will be able to hook their customers only when they are offering great customer support. I will give you an example, most web hosting companies give a free domain and free SSL as a way to attract customers, but with Namecheap, you'll need to buy SSL and domain, however, I am with Namecheap for years. Do you know why? Well, I am will Namecheap because of their support. When ever I encounter a problem, I can use live chat function and sort out my problem in 5 minutes.
