Question: When will you be shipping UMM-6s again? The day when I ordered mine there was a message at the bottom of the page saying they would be shipping the week of May 6... so today I visit the page and see the message has now changed to read they will be shipping in 7 to 10 days... problem is I don't know how long that message has been up there. Are those only 'working' days or they 'regular' days of the week? Will I get an email when it ships? Thanks.
