No...
However, if you have a Costco gift card you don't have to be a member to spend it in the warehouse.
I don't think so.
Not that i know of.
No ,but you can return it after a day "unsatisfied"
The only membership offered is a year. Costco does not do trials. But if you were to purchase a membership and you are unsatisfied they will refund you the full cost. Until the day of its expiration.
