Like Paul S., I have been going to Jumbo since it was at the Loblaws on Leslie and have since followed it up to Gerrard Square. Although the new location is far less convenient for me, I still make the trip to browse their fabulous selection.
I somehow always end up spending an hour in the horror section trying to narrow down to just 3 movies (for the amazing 3-movie deal). The choices available are extensive and they carry the best, somewhat obscure films. Just try finding a copy of Susperia at Blockbuster. I dare you....
