Wheel Covers

I have a 2000 Galant and the right rear wheel cover has fallen off. I have read online that this is a very common problem with 2000 Galants. I can purchase a new one for around $30.00, however is there anything I can do to avoid wheel covers from falling off???? I can't find any answers to this anywhere. Doesn anyone have any ideas?!?!? Thank you for your help.
