Hello young Phil and welcome to the house of fun.
Edmonton eh? Land of the Dave Clark Five and the moronic Bruce Forsyth. Sadly, there aren't many bricks and mortar places in and around town and what there are, carry a limited stock. You've got Myepack over in Thamesmead but I don't know if they are operate a collect service but you get your stuff in 24hrs from them. There's an outfit out near me in Dagenham somewhere that offer some very keen prices but with no physical address and not even a phone number I certainly wouldn't recommend them.
As has been said, you won't go wrong with a Protank 2 or a Davide. They hold 2.5 ml or so of juice so not bad for a light vaper. Also, if you bought replacement heads for the Evods, they'll also fit the Protank.
Got to go, the Vuelta's on.
