These aren't "sales" they are releases of a highly anticipated product. We don't announce specific times or dates anymore because of all the issues that happened in the past. (Check the old customer service thread lol) Previously when we announced specific time people would constantly refresh the page and crash the whole server causing hours of frustration.
The US presale was dived into 3 different parts specifically to give people multiple opportunities to grab the set. It would've sold out in the first 30 minutes if we announced one specific time and date. In addition to the presale there is a general release where you have a 4th chance to snag some of the new drops. The first presale drop was announced via newsletter, and the site opened just a few minutes later. All this info was clearly stated in the Presale post.

The Canada market is quickly growing and its hard keeping up with demand. The Reservas didn't sell out but our stock of freebies ran out in the first two hours of store opening. So we closed shop and will reopen when another round of freebies shows up. International mail is still unreliable so getting stock to Canada is still a bit cumbersome.
