2x Sound of Music Tickets Dec 3: DATE SWAP?

I bought 2 Sound of Music theatre tickets for me and my mum for Tues Dec 3 7:30pm at the Stanley Theatre in Vancouver. My mum now can’t make that date. Anyone want to swap to another day??? I’ll pay $20 for the swap for any seating or more for good seating. Can do most days after the 4th except 21st-27th. If I don’t find a swap, I may sell for good rate. Message me if you want to be on standby.
