International shipping available - prices for under 120 switches should be between $8 - $10 in a padded mailer. Over 120 switches may need to go into a box which raises prices dramatically. If you have questions on shipping, please e-mail: contact[at]mehkee.com
Timeline: switches are expected to arrive ~June 7th and ship in the 1-2 days after. If there is excess demand, I will place another order and have it rush shipped.
