I'm terribly sorry if my message came across as rude - it's a bit hard with email sometimes to get a sense of tone. :-)
I'm very appreciative of all the hard work and time you've put in so far - you've been very accommodating and your responses have been timely and very helpful.
I'd be very grateful if you could send me the spare parts that I critically need to make my laser work as advertised. Of course, you'll send them by normal post - I can certainly wait to receive them.
If you could please tell me when you've sent it, that would be awesome. Also if there's any tracking numbers can you please let me know.
Thanks again and have an awesome day. :-D
