Do they offer a plan for couples?

No

Yes

My husband and i pay the same singles fee per moth but he had no additional f ees to join. Thats the only "discount"

Even if you take out a family plan, you still get billed as individuals.

Yes. You can get a family plan if you like.

I signed up with my husband and it benefited us to do it together vs separate. There was no fee or contract.

Call the store.
