The shop will be open for the next three months, and features a range of club merchandise, replica kit and clothing for supporters and their friends and family to stock up for the festive season.
There will be more opportunities to meet Crystal Palace players over the festive season, with plans for further events to take place in the heart of the community.
Speaking at the event, Mamadou Sakho said:“We have great fans. They are always behind us when we are playing away or at home, we need them and they are always with us. When we are at home we are playing 12 against 11.”
The shop is open seven days per week, and will be open until January 2019.
