Also keep your eyes open at Sally's Beauty Supply as I got a buy 2 get 1 free deal on Ardell lashes the other day. They always have great sales and its really worth it to get the discount card its only $5.00 cdn and you really do end up saving.
If you are looking for a great online site to purchase your lashes may I suggest... I Heart Red Cherry. They have a wide selection of lashes for amazing prices (most being $1.29 us). However it may be cheaper for Canadians to ship to a friend in the US if you can as shipping costs can add up.
