Looking for a Rheem Marathon water heater on STX

I'm looking to find a Marathon water heater (new) on St. Croix. These are the insulated non metalic ones. Home Depot has them online but they are not available in our stores (weirdly--they seem perfect for our climate). I can order one but I'd like to give the business to a local business if possible.

Does anyone know if a local store stocks these?

Thanks
