There are plenty of Speakout users, particularly in the Ottawa/Quebec/East Coast thatno longer have 7-11 stores in their area. The service still work, provided you can get vouchers. Thats why they buy them here. As to why guys are selling $50 vouchers for $50, you got me??? You have to pay tax on those things, so they are actually selling at a loss.
Why can't we buy airtime online? Since SO and Petrocan are run by the same operator, I can only assume that 7-11 wants to draw customers in to their stores. PC has an online option, so I can see no other reason why SO wouldn't.
PS, I could read your post, so I assume your math was perfect
