Rob - the invoice was only sent last night, and if I recall, you don't check your hotmail account until after work today, correct? That's why you haven't seen it. Please email me offline
admin@grandlsambids.com if you want to continue this discussion so I can help troubleshoot with you.
It's not a hotmail issue as best I can tell as I know of at least 2 other users using their hotmail account who have correctly received all emails sent.
