1. Yes
2. Anything that is able to liquidate fast and not much discount. i would recommend that you buy anything that you could sell on "craigslist" instead of ebay or amazon since they take 10-15% and you have to ship it.  examples are:computer components Core-i7 cpu etc
3. no i use my heavily used real name, real address account. I do one SE every 3-5 orders. Most of them are above 500$ and below 1500$ and most of them are not signature required.

For things like computer components what method would you use, empty box or did not arrive?

i would say did not arrive. always work
i always use did not arrive.i do not use other methods.

Can you say did not arrive if you have to sign for it? What country are you from? And what is the process after you say it did not arrive?
