Point taken Mods.
Rhino: At point of closing the deal, I have taken note of all the accessories to be included, and yes I knew the neck strap and box are not included("lost"). Like I stated, 30 mins prior to agreed meeting time, he told me that the dry box was spoilt. I am not that petty to cancel a deal over a cheap dry box. The main point is not about my expectation of the items in the list, but rather his behaviour and etiquette of a seller.
From the start of the meeting he was acting rushed and would only permit a short duration for the dealing. I asked if he want to deal somewhere where I could do a proper check(note: carpark is dim and may conceal any imperfection not declared). He said no, I said fine. I repeated some questions I asked him over SMS - such as confirming the box and receipts to be lost because of "moving house", and asked him to be understanding while I did checking of the dSLR and to make sure nothing is illicit. If you have done purchases from sellers before, you know very well what the question are typically about - regarding the items in question. He did not even have any hard copy documents like warranty printout or whatever proof of ownership he has(apart from a few digital images which can be faked anyway). If you are buying something, you will typically insists on something hardcopy even if its not a receipt or a box.
He started becoming unreasonably urgent and acting suspiciously, giving me an ultimatum to buy it "right now" or the deal's off. I asked for 5 minutes to do a quick check and he obliged. Everything's in order, and as for serial number checking I do not know of any way to check the serial without plugging it into the PC or bringing to service centre, and the seller's rushing didnt help either. The final crux came when he did not even have change for $50, and decided to cancel off just like that. What kind of seller etiquette is that?
Within the span of 5 minutes, it is difficult to think it over and trust my own instinct. Only when it was over did I think that his behaviour over the course of dealing was suspicious as if he was trying to avoid me trying to find out something illicit about the deal and all. Only if u piece everything together, the lack of some thing can be suspicious
