Questions from Castlewood business owners
With 739 people in Castlewood, is a website worth the money?
Your customers come from all of Hamlin County, not only Castlewood: the county has 213 businesses with employees and 553 without (2023). The website is what they find when they search.
Can I show customers in Goodwin that I cover their area?
Yes. Send the list of towns you serve by email (Goodwin, Estelline, Hayti or any others) and the website gets a service area page with all of them.
Can customers buy from my website?
Yes. An online store with catalog, cart and online payment costs the same $89 a month as a regular website; sales tax is yours to collect (South Dakota’s state rate is 4.2%, and local taxes may apply).
Is there a setup fee?
No. No setup fee: you only pay the $89 monthly fee, after you approve your website. There is no lock-in contract either: you can end the service whenever you need.
