no need to get worried. What i mean is. out of practice. r whyte dont post parcels if there is a chance that they wont arrive before the weekend. i.e so that it's not sitting in a van on sunday when everyones off. They will prob post on monday and it will arive on tue. thats what happend with mine.(good idea if you ask me. i think its amtrak post)
And i mentioned the invoice because when i recived mine the invoice was not with it(they must have missed it) so i phoned up and they posted out another copy.
again don't worrie, it's a good company and a good projecter.
and if they have stock in, you'll be enjoying your projecter by wed.
And if there's a fault you have a years garantee.
After about 9 months i would look into getting an extra years garantee of sony, about £90, but worth it for the POmind
