Can I buy gift certificates for Nebraska crossing that can be used at any of the stores there? Or do I have to buy ones just for particular stores?

Yes at the outlet managers office. They are good at any store

Probably for each store but you could ask

Particular store only i think

I'm not sure

I don't know. I would imagine there is a corporate office there somewhere that you could. Might try seeing if there is a phone number and call them with your question.
