How big is the mall? 8 stores could really not be that bad for competition you just have to spend a bit more time marketing and getting people to your store.
Back in '05 when I worked at the Deerfoot Outlet Mall in Calagary (ever been there?

) and at that time the mall had:
- Telus Store
- Telus Kiosk
- Bell Kiosk
- Rogers Store
- Fido Kiosk
- Source (Rogers)
- Radio Shack (Telus & Bell)
If you didn't count the food court there were probably a total of 30 stores (that's being generous!) and 7 sold cell products. Our store did great, we just found that after more stores moved in we just had to spend more time getting people to come to us and close hard!
If you don't mind me asking what kind of targets did they want you to hit to gain your bonuses and/or keep them happy?
