Network Solutions offers a 30 day money-back guarantee, which essentially functions as a free trial. Here is the fine print on the agreement:

* Offer valid with new purchase of one year hosting package. Free domain name is limited to a 1 year term and is available for new domain registrations, domain renewals and domain transfers of .com, .net, .org, .us, .biz, .info & .name extensions. Term of the free domain will match the term of the hosting package. Only one discounted domain is available per order. If you wish to purchase an additional package and receive a discounted domain, please complete a separate transaction.

A 30 day money-back guarantee is pretty standard among web hosts. This is a great insurance policy, giving you the chance to try out a web host risk-free. For more information on Network Solutions hosting, check out the following videos:
