No me ha regalado nada material ________ ha reservado un billete para Cancún para dos. He diI thought n't give me anything material but he booked a flight to Cancun for two.sino quesinopero

I thought long and hard before answering this onr.  Although it fits the patter nor using sino que, if is a  correctionof  the first statement, the second statement is a contrast:  something practical rather than something material.  It is ambiguous depending on the circumstances and "pero" can be used following both positive and negative first statements.
