[Dog Star (Phil)]

Recently decided I needed another set of binoculars.
After doing some web searching, I found what looked to be just what I needed at the right price. The company (Vendor X, shall we call them) don't list a phone number, so I sent off an email to ask about their transport details, something that you need to know when living in a hard to find place 20 k's outside Alice Springs. I mentioned that I really wanted to make the purchase (not window shopping) and would appreciate a reply.
Sent my email on the 15/01/09 and a reply (automatically generated, I assume) was in my inbox the next day telling me that they were on holidays until 27/01.
Although it was a longer wait than I had anticipated, I thought I'd wait as opposed to ordering through another vendor as I really wanted what Vendor X had for sale. Vendor X, I should add, is a reasonably well known Australian vendor, and is NOT Bintel or Andrews.
I had assumed that I would have received a reply by the close of business on the 27th, but when I hadn't, i figured that they were catching up after the holidays.
When I still hadn't received a reply by close of business on the 28th, I sent another polite email asking if I could get a reply to my first email.
By close of business today (29th) I still haven't received a reply.
Would I be correct in assuming by now that Vendor X just isn't interested in doing business with me?
I'm a bit new to this ordering stuff by email, so I'm not sure what is "acceptable" by way of business etiquette. Do I have the right to be ticked off, or is this just standard procedure?
Do I just give up on Vendor X and shop elsewhere?
Your thoughts would be appreciated.
