I was going to translate it later so that you wouldn't end in a naïve sudden problem with your beloved husband.

OK, if I am here, I could go along with you and help you with this matter. If not:

"Buenos dias, ¿Tienen ustedes (e)sfig*******whatever?"

"Cuanto cuestan?"

"Los tienen aquí o tienen que encargarlos?"

"¿Para cuando los tendrán?

¿donde puedo conseguirlos?

If your husband comes too, I remember he can speak a reasonable spanish.

P.S.: (Thank you for taking well the joke, I was a little uneasy). A cheek kiss.
