The only complete ski shop near the town lift is Bahnhoff on Main St, There are other shops in the vicinity but they specialize in rental demos without a real inventory of new skis. I don't know Bahnhoff's policy but it is typical here for at least one day of demos to be applied to the purchase price. Bahnhoff is a good shop but by February they could be picked over so you should call beforehand for availability, specifics and possibly reservations.
Another option would be Cole's at the base of PCMR. It would be a simple cab or bus ride initially but you could ski back to town thereafter. The bus transit center is close to the town lift with frequent departures and a 5 minute ride.
The best demo experience however might be Christie's in Silverlake Village at Deer Valley. Last season you could demo as many skis as you cared to during the day and the cost was applicable. I have not stopped by Christie's this year.so I don't know their current situation. Christie's is very close to lifts so switching skis would be fairly simple. There are buses running from the transit center to Silverlake regularly although perhaps not as regularly as for PCMR so I would check the schedule.
If you consider these other options I suggest calling in advance for terms, availability and reservations.
